Remote Desktop Plus

Once upon a time in a company far, far away, I needed to find a way to have users automatically logon to a Remote Desktop session with a specific set of credentials. I searched everywhere, and although I did find some tools, none of them were exactly what I was looking for. So I decided to make one myself. With the help of a lot of information on the web, I managed to write my own utility, saving me tons of work.

Having done that however, I saw more possibilities. So as a way to spend what little free time I have left, I started writing Remote Desktop Plus. It’s Remote Desktop, but with some added features. Basically it allows you to launch a Remote Desktop session using a username and password entered from the command line (autologin) or imported from a saved profile. But that’s not all…

Features #

  • Login automatically from the command line.
  • It’s free. :-)
  • Supports launching and autologin of RemoteApps.
  • Remote Desktop Plus (RDP+) is not a clone or copy of Remote Desktop. It’s just a shell for the normal Remote Desktop client (mstsc.exe) on your computer.
  • Automatically trusts all local resources and the remote computer. No more annoying questions like: Do you trust the computer you are connecting to?
  • Allows you to save credentials (securely) in profiles. Profiles normally only work for the user who saved them and only on the computer on which they were saved. Profiles can be useful when administering a large amount of computers from a single point of administration. Changed the password for Administrator? Just edit the profile and you’re done.
  • Passwords entered from the command line can be encrypted for enhanced security. Useful when starting Remote Desktop from batch files or published applications (Citrix).
  • Remote Desktop Plus features a special restricted kiosk mode in which only the computer, username, password, or any combination thereof can be changed. When used as a published application, this allows you to grant (internal or external) support departments remote access to a range of servers in a much safer way.
  • You can specify a range of computers the user is allowed to connect to. Any attempt to connect to computers not in the list will be denied.
  • Ability to save frequently used connections as favorites for easy launching.
  • When logging on to a computer with local credentials, Remote Desktop Plus will try to determine the actual computername, so you don’t have to specify a computername in front of the username (like nldb01\sa). This is also useful when logging in to computers using an IP address instead of a computername (rdp /v: /u:administrator) or when logging on to Windows clusters.
  • Supports connecting through a Remote Desktop Gateway server.
  • When using custom .rdp files, RDP+ will save valuable text space in the task bar by not displaying the name of the .rdp file in the title bar.
  • Accepts both /console and /admin. No need to remember which version of Remote Desktop and/or which Service Pack for XP you’re running.
  • Can set the working screen size to either the maximum available size (so it looks like a normal maximized application) or to a adjustable size – by setting either a margin or specifying a percentage of the screen – so you can still move it around a bit.
  • When using multiple monitors, you can specify on which monitor the Remote Desktop session should be started.
  • Supports specifying a startup program (i.e. alternate shell) from the command line. You can use both local and remote environment variables in the command.
  • Features an optional system tray icon for launching and managing your favorites, and for quickly switching to currently active Remote Desktop sessions.
  • Launch favorites from the command line.
  • Normally Remote Desktop times out after about 30 seconds when connecting to a non-responsive (or still booting) computer. But the age of modems is a thing of the past and time is precious, so Remote Desktop Plus times out after only 3 seconds.
  • You can set your own title bar text and specify your own icon.
  • Has the ability to disable the close button in the title bar and remove the connection bar, thus forcing users to logoff gracefully instead of just disconnecting and leaving their remote sessions open.
  • Allows you to specify in the command line which drives or drive types to redirect and/or which drive(s) to exclude from redirection.
  • Ever had to login to multiple servers at once? Just enter those servers separated by commas and off you go.
  • Remote Desktop Plus also has a load balancing and failover feature. Specify multiple servers and RDP+ will randomly pick one of the servers to connect to. If this server is unreachable, RDP+ will skip it and cycle trough the other servers in the list, until it finds a responsive one. You can use this for example for legacy RemoteApps which are hosted on multiple servers without a session broker.
  • Has the ability to log all connections in a log file or the event log.
  • Still missing some command line parameters? RDP+ supports every option supported by the Remote Desktop .rdp file, using a special command line parameter. This gives you an unprecedented control over every aspect of the session, straight from the command line and without the need for specific RDP+ command line switches.
  • Some settings and options can be controlled through Group Policies. Group Policy templates for these settings are available for download on the site.
  • RDP+ has a very small footprint. It consists of a single file, less than 250 KB. No installation required on the client.
  • Contains no spyware, adware, browser toolbars, nag screens, phone home mechanisms or any of that stuff. And it never will.
  • And much more…

Myself, I use the second example the most. Just create a shortcut in your Quick Launch toolbar and you only have to enter the desired server name.

Notes #

Profiles #

Normally profiles are saved with the highest level of security, which means they can only be used using the account which created them and only on the computer they were created on. As of version 5.0, you can now also save profiles using a less strict security, which means they’ll be available on any other computer and will ‘roam’ with you. Please note however that because no external password key is used, a determined individual with the right tools (debuggers, disassemblers), the right knowledge of programming, access to the registry or computer of the user, and some other ingredients, could potentially break the encryption, so use this option with care.

Also new is the add-on tool RDPProfile.exe, which allows you to automatically create profiles from the command line. You could use this from a login script to pre-populate some profiles for end users.

Startup program #

If you need to use double quotes in the /start startup program, you have to put a backslash (\) in front of each quote. You can also use environment variables in your command, both local and from the remote computer. To use remote environment variables, you must precede the percent signs with a backslash.

Combined example: rdp /v:nlapp03 /u:donkzdomain\helpdesk /start:""C:\Program Files\Remote Control\rc.exe" "\\nlfps01\Config$\RC\\%COMPUTERNAME\%-%USERNAME%.cfg""

If Remote Desktop Plus is started by user JohnDoe, the last part of the command will be expanded to "\\nlfps01\Config$\RC\NLAPP03-JohnDoe.cfg".

Title #

You can set a user defined text as your title bar by using the option /title. You can use local environment variables in your title plus these two special variables:
%s: Will be expanded to the server name you’ve connected to.
%u: Will be expanded to the username used to login to the remote computer.

Example: rdp /i:"Domain Admin" /fit /title:"%s (%u) – Remote Desktop"

When connecting to the server nlfps01, this would result in the title bar text nlfps01 (DONKZDOMAIN\Administrator) – Remote Desktop.

Icon #

You can also use your own icon for the session by using the option /icon. This can be either a normal icon file (G:\Icons\Remote.ico) or an executable or .dll file (%ProgramFiles%\Internet Explorer\iexplore.exe). For files containing multiple icons, you can specify the desired icon using its index (%WINDIR%\System32\shell32.dll,43).

Please note that using /icon will also force an implied /wait, due to the way Windows retains (or does not retain) dynamically changed icons when the program which requested the changes is closed.

RemoteApps #

You can start a RemoteApp with Remote Desktop Plus, either from the command line or specified in the .rdp file. You can enter the RemoteApp using either its name ("||FileZilla") or the full path to the executable (C:\Windows\System32\Notepad.exe).

When using the name, always enclose it between double quotes, otherwise your system may confuse the double pipe signs with the double pipes used in batch scripting.

All options concerning the screen (like /fit and /mon) are ignored when using RemoteApps. The same goes for /title and /icon. 

Due to the way the Remote Desktop client launches all RemoteApps in a general, embedded instance of mstsc.exe, the option /wait is also not supported.

Remote Desktop Gateway #

Remote Desktop Plus can login to remote servers through a Remote Desktop Gateway. There are no command line switches, so all options must be configured from the normal Remote Desktop client and saved in a .rdp file, or entered through the /o option.

When you select the option Use my RD Gateway credentials for the remote computer, RDP+ will also automatically login to the RD Gateway. If not, you will be prompted for credentials.

Kiosk mode #

With the kiosk mode, you can set the GUI to a special restricted mode, in which only the fields for the target computer, username and password are shown. Using a 3-character ‘mask’, you can enable or disable any of the three fields. Each character in the mask stands for one of the three fields (computername, username, password). A 1 will enable the field, a 0 will disable it.

For example, /kiosk:011 will disable the computername field and only allow the user to enter the username and password.

The kiosk mode will default to 100 when a mask has not been specified.

Allowed targets list #

Using the /allowed command line option, you can restrict users to only a selected range of computers. If the user tries to connect to a computer which is not in the allowed target list, the connection will be denied. This can be especially useful for publishing RDP+ to ‘untrusted’ users.

You can use both wildcards and regular expressions in the list. RDP+ will also try to translate hostnames to IP addresses and vice versa for its matching. So for example, when using /kiosk:100 /allowed:127.0.0.*, a target computer of localhost will be considered valid.

Enclose targets in parentheses to use regular expressions. Environment variables are also supported.

Example: rdp /allowed:"10.10.*.*,nlfps*.donkz.local,(nl(app|db)\d{2}(%USERDNSDOMAIN%|))"

Note: When using the pipe sign (|) in a regular expression, be sure to enclose the entire string in double quotes to prevent conflicts with batch scripting.

You can also use the /listallowed command. This will transform the editable computer textbox in the GUI to a listbox with only the allowed computers listed. This can be more user friendly for third parties. Please note however that wild cards and regular expressions are not supported in this mode.

Drive redirection #

You can specify the drives you want to redirect to the remote computer by using the /drives option. Drives can be specified either by name or by drive type (Fixed, Removable, Network, CD-ROM). To redirect drives that get plugged in later, you can use the drive type Dynamic.

You can also exclude certain drives by preceding them with the minus sign. For example, /drives:fixed,-c:,p: will redirect drive P: and all fixed drives except C:.

If you don’t specify any drive or type, /drives will default to all drives, including the ones plugged in later.

Extended .rdp options #

By using the /o switch, you can specify every option supported by the .rdp file. Options should be given in the exact same syntax as used in .rdp files.

You can specify multiple options by separating them by commas. To use commas within options, precede them with a backslash.

Examples: rdp /start:terminal.exe /o:"shell working directory:s:H:\My Documents, redirectcomports:i:1″ rdp /remoteapp:"||ProdDB" /o:”remoteapplicationcmdline:s:proddb, sqlsa, P@ssw0rd, remoteapplicationname:s:Production Database”

The native RDP+ command line switches always take precedence over the /o options. So if you use rdp /printers /o:"redirectprinters:i:0″, then /printers will win.

For an overview of (most of) the possible settings, you may find this page useful.

Log file #

You can log all started sessions to a semicolon-delimited log file using the /log option. If you don’t specify the name of the log file, it will default to the file rdp.log in the directory containing rdp.exe. If you do specify a filename, the name can be further customized through both local environment variables (like %COMPUTERNAME%), and some special variables:
%s: Will be expanded to the server name you’re connecting to.
%u: Will be expanded to the username used to login to the remote computer.
%c: Will be expanded to the name of the local client computer. When starting RDP+ locally, this will be the same as %COMPUTERNAME%. When starting RDP+ from within a Terminal Server or Citrix session, %c will contain the computername of the originating client computer (i.e. %CLIENTNAME%).
%y: The 4-digit representation of the current year.
%m: The 2-digit representation of the current month.
%d: The 2-digit representation of the current day.

Example: rdp /log:%y%m%d-%s.log

When connecting to the server nlfps01 on the 31st of December, 2011, this would result in the log file 20111231-nlfps01.log being used.

The log file contains all kinds of information about the computer and user which started the session, and information about the target computer and how the session was started. When RDP+ is launched from within a Terminal Server or Citrix session, it will also log the computername and IP address of the originating client. This can also be useful when using thinclients. A typical log file could look like this:

System tray icon #

RDP+ features an optional system tray icon. This icon can be used for the following things:

  • Managing and launching favorites.
  • Starting a new ‘blank’ instance of RDP+.
  • Quickly switching to currently active Remote Desktop sessions.
  • Automatically load the tray when you start your computer.
  • See which Remote Desktop session you had active last, or by doubleclicking the tray icon, immediately switch to the last active session.

When using the kiosk mode, the system tray reverts to a simpler mode, in which only the active sessions are available. This simple mode can also be enforced through the Group Policy.

Favorites #

When creating favorites, you have the option to save them with the option Save secured (user and computer bound). This means the favorite is only available on the computer it was created on. Use this option when you have specified sensitive passwords in the command line.

When not saving it as a secure favorite, the favorite will be available on any computer you logon to when using roaming profiles. It will be saved using the same encryption /pe or Gencrypt uses, so it is still secure from prying eyes.

Command file #

If you regularly use the same command line parameters, you can also put them in a separate file and specify this file with the @-parameter. RDP+ will then use the contents as its command line parameters. You can also put normal .rdp file style options in the command file, without having to precede them with /o. This way you can use the command file as a master .rdp file.

Comments can be added by starting the comment line with a semi-colon.

Example of a command file:

; Command line
/fit /noprinters /drives:fixed /icon:Company.ico /title:"%u on %s – Remote Desktop"

; Default .rdp file options

Tip: Use .rdpc as the suffix for the file and run RDP+ with the command line /register once to register the .rdpc extension to RDP+. This allows you to double click command files to immediately launch RDP+ and have the command files shown in the recent files when pinning RDP+ to the Start Menu.

Exit codes #

When starting Remote Desktop Plus from a script, you can use the option /batch to prevent RDP+ from displaying error messages. Instead you can catch potential errors through the exit codes (errorlevels) which RDP+ raises.

These are the possible exit codes which can be raised:
0: No errors.
1: General undefined error.
2: Specified connection file not found.
5: Target computer not in the list of allowed targets.
29: Cannot write to the log file.
30: Profile not found.
87: Invalid command line parameter or combination of command line parameters.
161: The format of the specified path is invalid (filename of the connection file, log file or command options file).
259: No responsive server found in the list (when using /lb).
2382: Invalid notation of the specified host name or IP address.
10060: Connection timed out to the specified server.
11001: Remote hostname not found.

Please not that exit codes are only raised when RDP+ is either started with its own /wait command line switch or when you launch RDP+ from a script using the appropiate syntax to wait for completion.

Examples of the latter:


START /WAIT rdp.exe blah blah


Set objWSH = WScript.CreateObject("WScript.Shell")
Shell = objWSH.Run("rdp.exe blah blah", 1, True)
WScript.Echo Shell


$Shell = Start-Process -FilePath "rdp.exe" -ArgumentList "blah blah" -Wait -Passthru

Setting default options #

You can set some of the command line options as the default option for Remote Desktop Plus by setting the user environment variable RDP.

Currently supported are the following options: /w/h/fit/f/fullscreen, /multimon/pos/max, /mon, /[no]printers, /[no]drives, /[no]sound. [no]wallpaper, /log, /eventlog, /t, /tray and /register.

For example, you can set RDP to /fit /mon:2 /noprinters /drives:fixed.

When you set /mon to a number higher than the number of monitors attached to your computer, RDP+ will automatically fall back to monitor 1. This means you can safely set it to 2 if you always want your session to start in the second monitor when it is available.

The default options can of course be overruled by entering the option you want in the command line. To override the display size with the fixed dimensions from the .rdp file, you can enter either specify /w or /h in the command line, without a dimension.

New in RDP 6.0 is the ability to set these options using the registry key HKEY_CURRENT_USER\Software\Remote Desktop Plus\DefaultOptions or HKEY_LOCAL_MACHINE\Software\Remote Desktop Plus\DefaultOptions.

Localization #

As of version 5.0 you can localize RDP+ for your own language using a customizable XML file. In the download section you will find a Dutch template (language_nl.xml) which you can use to create your own translation. Once you’re done,  save it in the directory containing rdp.exe and replace the template part in the file name with the two letter (ISO 639-1) language code for the language your computer is running.

For example: language_de.xml for German.

If you’d like to help translate RDP+, you can send your completed XML files to and I’ll put them up in the download section.

Group Policies and registry #

Some of the behavior of Remote Desktop Plus can be controlled through Group Policies or registry settings. More information about this can be found on this page.

Order of preference for commands #

RDP+ supports many different ways for specifying commands or options. These are processed in the following order:

  • Value of HKEY_LOCAL_MACHINE\Software\Remote Desktop Plus\DefaultOptions.
  • Value of HKEY_CURRENT_USER\Software\Remote Desktop Plus\DefaultOptions.
  • Value of the environment variable RDP.
  • Content of the command file.
  • Command line arguments.
  • Machine part of Group Policy setting (Computer Configuration).
  • User part of Group Policy settings (User Configuration).

Last setting wins.

System requirements #

  • Windows XP/2003/Vista/2008/7/8/8.1
  • Microsoft .NET Framework 2.0 or higher

Note: If you intend to launch Remote Desktop Plus from a local network share and you’re running a version of .NET Framework prior to 3.5 SP1, you’ll need to execute the following command once from the command prompt:

%windir%Microsoft.NETFrameworkv2.0.50727caspol -q -m -ag LocalIntranet_Zone -zone Intranet FullTrust -n "Network shares" -d "Full rights in Local Intranet zone."

If you only have .NET 4.0 installed and no previous version of .NET, Remote Desktop Plus (or any other program targeted for previous versions of .NET Framework for that matter) will fail to launch with an error Unable to find a version of the runtime to run this application. You don’t necessarily have to install an older version of .NET to fix this however. Just create a file named rdp.exe.config with the following content and place it in the same directory as rdp.exe:

                <supportedRuntime version="v4.0″ />

Alternatively, you can download a ready-made rdp.exe.config from the download page.

    Hi, I am using this tool every day for a few years now (since version
    Just installed 6.1 and am happy for its existence :)

  • Paul

    I saw one of your features was:
    * Remote Desktop Plus also has a load balancing and failover feature.

    Is it possible to have a list that the client checks to see if the remote computer is in use and then moves on to the next one in the list? It doesn’t have to be sequencial it can pick randomy but I really want it to use the local credentials and if an error ‘in use’ is returned it attempts to connect to another?

    Hi! Is there a way to close existing connection run with these parameters: /v:address /u:login /p:password using c# or command line?

    To URI : To start a program, Windows must allow it.
    (I faced the same issue several times).
    For 2012 server :

    use Local Group Policy Editor (gpedit.msc)

    Computer Configuration/Windows Component / Remote Desktop Services / Remote Desktop Session Host / Connections

    Allow remote start of unlisted programs –> set to ‘Enabled’

    this should help :-)

    Here’s on 2008 server.

  • Hi, I’m trying to start a program using the /start option.
    I’m trying: rdp.exe /v:myMachine /domain:myDomain /u:myUser /p:myPassword /start:"C:\Users\myUser\Desktop\Run_Jenkins.bat"

    but nothing happens. I also tried some of the examples above but still without success.
    Any ideas??

      See my detailed comment above (I missed the ‘reply’ button).
      It’s a rights problem, use Local Group Policy Editor
      go to Computer Configuration/Windows Component / Remote Desktop Services / Remote Desktop Session Host / Connections
      enable ‘Allow remote start of unlisted programs’

      enjoy ;)
