More than one RDP session per user on Windows 2008

Just saw an awesome post on a Dutch site that I noticed before, but never really took the time to investigate further:

It appears Windows 2008 (and noticed the same thing with 2008 R2) by default only accepts one RDP session per user. So when administrator logs in, he could potentially kick out another person who uses the administrator account. 

So Rudolf Kleijwegt posted the following command:

reg add "HKLM\SYSTEM\CurrentControlSet\Control\Terminal Server" /v fSingleSessionPerUser /t REG_DWORD /d 0x0 /f

AWESOME tip, and I'll definitely add this to our buildserver.
