Enabling Multiple Remote Desktop Sessions in Windows XP Professional and Media Center Edition 2005

If you have ever used a real remote computer system like Citrix, then you have probably been craving multiple Remote Desktop sessions since you first fired up Windows XP Professional and/or Media Center Edition. Here is a HACK (translated: USE AT YOUR OWN RISK), to enable multiple Remote Desktop sessions on your XP Pro or MCE 2005 box:

NOTE: You will have to have knowledge of the Windows operating system and more specifically the Windows Registry. If you have no experience with the registry, then I would recommend you find someone who does or leave these alone. I do not make any kind of warranty that this will work for you or your friends. This is provided for entertainment purposes only. Don’t call me if your computer stops working. Got it?

Print these directions so that you have them to work from.
Restart your computer in Safe Mode - Follow this link to learn how to restart Windows XP in Safe Mode
Turn off/disable Remote Desktop Connection (RDC) and Terminal Services
Right click My Computer
Select Properties
Click on the Remote tab at the top of the window
UNCHECK the box next to, “Allow users to connect remotely to this computer“
Click OK
Go to Start -> Control Panel -> Administrative Tools -> Services
Find Terminal Services in the list
Right click on Terminal Services and click Properties
In the Startup Type box, select Disabled
Click OK to close the window
Next you will replace the current version of the Terminal Services DLL (termsrv.dll) with an unrestricted version from a previous release of Terminal Services.
Here is a copy of the Terminal Services DLL - Save it to your Desktop or other suitable location
Using a file manager like Windows Explorer open C:\Windows\system32\dllcache
Rename the file termsrv.dll to termsrv_dll.bak or whatever you would like.
Copy the downloaded termsrv.dll file (the one you just downloaded from the web) to C:\Windows\system32\dllcache
Open the C:\Windows\system32 folder
Delete the file termsrv.dll in C:\Windows\system32
Now we can edit the Windows Registry to enable more than one RDP connection. Go to Start -> Run and type regedit - Hopefully you knew that already
Go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Terminal Server\Licensing Core
Add a DWORD Key named EnableConcurrentSessions and give it a value of 1
Close the Registry Editor window
Go to Start -> Run and type gpedit.msc to run the Group Policy Editor
Browse to Computer Configuration -> Administrative Templates -> Windows Components -> Terminal Services and double click Limit number of connections
Select the Enabled button and enter the number of connections you would like to enable….at least 2.
Restart Windows
Right click My Computer and select Properties.
Click on the Remote tab at the top of the window
CHECK the box next to, “Allow users to connect remotely to this computer“
Click OK
Go to Start -> Control Panel ->Administrative Tools -> Services. Select Terminal Services from the list and double click it or right-click -> Properties. Set the Startup Type to Manual.

Restart Windows/Computer
You should be good to go
