Like most IT professionals, I’ve been using Bginfo to embed some useful information in the wallpaper of a users Desktop for some years now. So what you say! Well…not too long ago Warren Simondson of CTRL-ALT-DEL IT Consultancy created a couple of cool utilities called TSBackdrop and PCBackdrop. I was specifically interested in the TSBackdrop utility, as it automatically displays items such as the Client Computer Name, Client IP address, Username and the Server which the Client is logged on to, on the user’s desktop background. This is great for Terminal and Citrix servers, and something that Bginfo lacks.
However, I wanted the best of both words; the ability to display ordinary text, as well as displaying this useful client connection information on the user’s wallpaper. This is now easily achievable with thanks to the lastest release of Warren’s tools.
So my challenge was to first run Bginfo to create an updated bginfo.bmp, and then use TSbackdrop to reference the bginfo.bmp and create a TSBKDRP.BMP in the users “My Documents” folder. I basically wanted the desktop to look something like the following screenshot (without the red boxes of course).
So to achieve this I needed to copy the following 4 files to each Citrix server:
- Bginfo.exe
- Standard.bgi (the Bginfo template)
- TSBackdrop.exe
- ResetWallpaper.vbs (my script, which is what this article is all about)
You also need to place a Shortcut to the ResetWallpaper.vbs script in the “%ALLUSERSPROFILE%\Start Menu\Programs\Startup” folder, so that it runs every time a user logs in.
Be sure to set the Target of the shortcut to %SystemRoot%\system32\cscript.exe //nologo “%ProgramFiles%\BGInfo\ResetWallpaper.vbs”
…and the Start in to %ProgramFiles%\BGInfo
You can place these 4 files anywhere. I have always placed them in a “%ProgramFiles%\BGInfo” folder. Hence the references to it in these scripts.
This is all handled by the following InstallBGInfo.vbs script.
‘ BGInfo and TSBackdrop installation script.
‘
‘ For Terminal/Citrix Servers we are using a combination of SystemInternal’s BgInfo and
‘ CTRL-ALT-DEL’s TSbackdrop to create a nice informative wallpaper for all Terminal/Citrix
‘ server users. The BGInfo.bmp file is placed in their %TEMP% folder and the TSBKDRP.BMP
‘ is placed in their “My Documents” or “Personal” folder.
‘
‘ Before we proceed we first need to check that the “Terminal Services” (TermServ) service
‘ is running, otherwise using the WMI provider to query the Win32_TerminalServiceSetting
‘ properties will return a null value. Note that the WMI provider namespace is slighly
‘ different between Windows 2003 and Windows 2008.
‘
‘ The script has also been structured to deploy to ONLY BGInfo to non Terminal/Citrix
‘ servers. In this case, the BGInfo.bmp file is placed in the %SystemRoot% folder.

So now we can display useful and informative information for users that will make it easier for them to differentiate between their “normal” desktop, and that of their Citrix/Terminal server session, or even a Virtual Desktop session, and also provide them with the relevant information needed when communicating with the IT Helpdesk Support Staff, such as their Client name, IP address, and server they are connected to.
How cool is that???
But wait…it gets even cooler!
I am also using Login Consultants ReconnAct! to run the ResetWallpaper.vbs script when a user reconnects to a disconnected session. This works well because if a user reconnects to a session from a different client, or they have obtained a new IP address, etc, this information will be “dynamically” updated on their wallpaper.
I have to end this article with some limitations:
- The TSbackdrop information would only display when positioned in the centre of the image. Warren has clearly documented this in the TSBackdrop.txt file.
- The TSBKDRP.BMP file can get to 2 or 3 MB in size, depending on the screen resolution of the session. This is also because I have BGInfo configured to create it’s bmp output file in True Colour (24 bit), and TSBKDRP.BMP bases itself on this. Since it’s placed in the user’s “My Documents” folder, this means that it’s typically located on a File server, and not local to the Citrix/Terminal server. Perhaps Warren can add an option so that it’s placed in the %TEMP% or “%USERPROFILE%\Local Settings\Application Data” folder. Then it remains local to the server, and does not get effected by roaming profiles and/or redirected folders. After all, it’s just made up of session information, relevant only to that server/session.
Some may think that I’ve gone to such enormous efforts for little gain. I strongly disagree. The use of these cool utilities, and implementing them correctly, adds to the useability and supportability of the overall solution.
Download the scripts in one convenient zip.
A couple of final comments.
- I have tested these scripts on Windows 2003 and Windows 2008 32-bit and 64-bit servers.
- Don’t use the wallpaper to display messages to the users. Too much background text is messy. You are better off using a Message Of The Day banner.
Enjoy!!!
