Windows XP Multiuser Remote Desktop

Windows XP Multiuser Remote Desktop
An interesting feature, on Windows XP, is the ability to be remote controlled from a second PC: the so called “Remote Desktop Connection” can be used from a dial-up connection or in a local ethernet network.

XP (and Media Center Edition), differently than the Server versions of Windows, has a limit: a single PC can be controlled by a single “local” user (the “real” person on place), OR a single “remote” user. If someone logs into the computer security from remote, the local user is disconnected. The following procedure deactivates this block and allows multiple persons to connect and to use a single computer from remote.
Very useful, for example, if you’ve a very strong PC and you want your wife/friend/brother to use an old computer like a “terminal” to use applications on the new one, at the same time of you. Other application of the same technique: you’re at work and you want to connect to your home PC, without blocking your wife that is using the same computer to check email

UPDATE: it seems that XP is limited, also after this modification, to 3 concurrent users. So don’t waste time trying to raise the maximum number of connections over three (see step 5) because, at this time, I don’t think there’s a way to use the same XP PC with more than 3 persons at the same time (e.g. a local user and 2 remote users).

This procedure is an “hack”: do it at your own risk:

STEP 1
Start your Windows in Safe Mode (tap on F8 first of the Windows Loading Splash Screen);
click on “My Computer” with right mouse button and choose “Properties”;
go to “Remote” tab and uncheck “Allow users to connect remotely to this computer” (if it’s already unchecked, just do nothing);
click OK.

STEP 2
Go to Start -> Control Panel;
open “Administrative Tools” and then “Services”;
double click “Terminal Services”, in the list;
choose “Disabled” for “Startup Type” option;
click OK.

STEP 3
Go to C:\windows\system32\dllcache;
rename the termsrv.dll file to termsrv.original or another name you like;
copy into the folder this unrestricted old version of termsrv.dll;
go to C:\windows\system32 (the upper folder of the current one);
do the same operation: rename termserv.dll also here, and put another copy of the file I linked above.

STEP 4
Click Start, then “Run…”, type “regedit” (without quotes) and press ENTER;
navigate in the Windows Registry Tree to reach this path:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Terminal Server\Licensing Core;
click with right mouse button on blank space in the right part of the registry window, choose “New” > DWORD, name the new key “EnableConcurrentSessions” (without quotes), then edit it and set its value to 1;
close the editor.

STEP 5
Click Start, then “Run…”, type “gpedit.msc” (without quotes) and press ENTER;
open Computer Configuration > Administrative Templates > Windows Components > Terminal Services;
double click “Limit number of connections”, choose “Enabled” and set the maximum number of concurrent connections you want to allow (2 or more), then Restart Windows in normal mode.

STEP 6
Go back to Remote tab of My Computer’s properties (see step 1) and activate “Allow users to connect remotely to this computer”;
Go back to “Terminal services” in “Services” (see step 2) and set its “Startup type” to “Manual”

Now restart Windows. Your operating system should be ready to accept multiple remote desktop connections
Remember that you’ve to prepare different Windows Users for every “phisical” user that want to connect to your desktop, to autenticate with separate logins/passwords. User accounts configuration is reachable in the control panel, and the list of users that can connect to the PC is editable in the remote tab of My computer

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?

1.Print these directions so that you have them to work from.
2.Restart your computer in Safe Mode - Follow this link to learn how to restart Windows XP in Safe Mode
3.Turn off/disable Remote Desktop Connection (RDC) and Terminal Services
1.Right click My Computer
2.Select Properties
3.Click on the Remote tab at the top of the window
4.UNCHECK the box next to, “Allow users to connect remotely to this computer“
5.Click OK
6.Go to Start -> Control Panel -> Administrative Tools -> Services
7.Find Terminal Services in the list
8.Right click on Terminal Services and click Properties
9.In the Startup Type box, select Disabled
10.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.
1.Here is a copy of the Terminal Services DLL - Save it to your Desktop or other suitable location
2.Using a file manager like Windows Explorer open C:\Windows\system32\dllcache
3.Rename the file termsrv.dll to termsrv_dll.bak or whatever you would like.
4.Copy the downloaded termsrv.dll file (the one you just downloaded from the web) to C:\Windows\system32\dllcache
5.Open the C:\Windows\system32 folder
6.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.
