Enabling Concurrent Remote Desktop Sessions in Vista
At work, I do all of my development on a Windows 2003 box. I generally log in as a normal user, and then use Remote Desktop to concurrently log in as Administrator. This means that I’m relatively safe from malware when doing day-to-day stuff, but that I can still get hold of Administrator privileges when I need them.
This feature is only enabled on server editions of Windows. When you try to connect to Windows Vista (for example), you have to disconnect the currently logged-on user.
This is taken more-or-less, directly from here, so I can’t take any credit.
You’ll need a hacked termsrv.dll, as follows:
fc /b %SYSTEMROOT%\System32\termsrv.dll termsrv_new.dll Comparing files C:\WINDOWS\SYSTEM32\termsrv.dll and TERMSRV_NEW.DLL 000150D8: 3B BA 000150D9: 91 00 000150DA: 20 01 000150DB: 03 00 000150DD: 00 90 000150DF: 0F 89 000150E0: 84 91 000150E1: 0C 20 000150E2: CA 03 000154BF: 43 90
(This one’s for Windows Vista Ultimate, x86 (i.e. 32-bit). And then you’ll need to install it, as follows:
cd /d %SYSTEMROOT%\System32 sc stop UmRdpService sc stop TermService takeown /f termsrv.dll cacls termsrv.dll /G DOMAIN\User:F ren termsrv.dll termsrv.dll.orig copy path\to\termsrv_new.dll termsrv.dll sc start TermService sc start UmRdpService
Note that if you want to connect to localhost, you’ll need to run some kind of port forwarding utility, and you’ll need to connect to it via 127.0.0.2.
