Multiple Concurrent Terminal Server Sessions On Vista SP1

14 Jun

There are several patched terminal server dll’s floating around in the net to allow multiple concurrent Terminal Server session on Windows Vista with Service Pack 1. But they all have the same limitations:

It’s not possible to start a session to Localhost, this is because the Terminal Server client does a check to see if you are running Personal Terminal Server (Vista/XP) and denies Localhost or 127.0.0.1 if true (127.0.0.2 works though).

It’s not possible to start multiple sessions with the same user. The patch for Vista RTM did allow for this but in Service Pack 1 some Terminal Server code has moved to the Local Session Manager (lsm.exe) so we need to patch this file as well.

Offcourse we need to patch Terminal Server to allow unlimited session on Vista as well.

VPatch files are in the download link below.

Is for 32 bit or 64 bit version?

This is for 32 bit.

Is there a 64 bit version available? Or instructions for manually patching the 64 bit versions? I don’t have the original 32 bit versions to patch, to then do a reverse engineer, to figure out how to mod the 64 bit versions.

Can we have two terminals using vista SP1
I mean can we get 2 monitors, 2 keyboards, 2 mouse, and a single CPU handling both the terminals?
While patching does it also effects the Vista in any other way?
And also which is the best OS available for using multiple terminals? Please provide few names so that I can pick 1 of the os later.

Someone patched the termsrv.dll for windows 7 beta and its possible to start multiple sessions with the same user.

for some reason I can´t get the same user to log in two differente sessions at the same time, it seems like the lsm.exe file is not working though i applied the patch on it, the file it generates has a 03/20/2008 date. Is there something I am doing wrong????
Can anybody send me a working lsm.exe file???

@abelurdis: Check your (local) policy with gpedit.msc, check Administrative Templates | Windows Components | Terminal Server | Connections and disable restrict users to a single remote Terminal Services session.
Also check registry under HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Terminal Server

You can replace the termsrv.dll for both 32/64 bit on Vista. See this post at http://oviya.me/?p=27

I try the patch_termsrv.exe in my vista sp1(which termsrv.dll version is 6.0.6001.18000), it pops msgbox “No suitable patches were found”.
