FWIW I needed to install this on kiosks in the field where booting into safe mode was not an option here is how I did it (I was doing this via a Remote Administrator session over a dial-up connection)... step 1 - use extract to extra termsrv.dl_ into termsrv.dll step 2 - create the following batch file (call it "copies.bat" that is in the same directory as termsrv.dll copy termsrv.dll %windir%\System32\termsrv.dll copy termsrv.dll %windir%\ServicePackFiles\i386\termsrv.dll %windir%\system32\dllcache\termsrv.dll step 3- use unlocker to terminate the processes that are locking termsrvc.dll. What you do this you will get window saying a severe error has happened in windows and that windows will reboot in 60 seconds. So onto step 4 before your 60 seconds are up... step 4 - run copies.bat.... The only reason we make the batch file is because you will be surprised how short 60 seconds is when you are fumbling around trying to make copies and delete files using windows explorer.. step 4a - let the machine reboot (or you can race to see how many remaining steps you can complete before your 60 seconds is up) step 5 - import the Concurrent Sessions SP2.reg (documented else where) step 6 - Make sure Fast User Switching is turned on. Go Control Panel -> User Accounts -> Change the way users log on or off and turn on Fast User Switching. step 7 - Open up the Group Policy Editor: Start Menu > Run > 'gpedit.msc'. Navigate to Computer Configuration > Administrative Templa tes > Windows Components > Terminal Services. Enable 'Limit Number of Connections' and set the number of connections to 3 (or more). This enables you to have more than one person remotely logged on. I had tried using tools like pendingmoves.exe to have termsrv.dll replaced on restart and several other things none of which worked. So I resort to unlocker... Terminal Services on win2k3 allows me to switch between terminal services logins via terminal services manager. I have heard people mentioning tha tyou can do the same on xp. How do I? I have not found anything similar to a terminal services manager in XP. thanks, Fizzy
