In Windows Server 2003 you could have multiple Remote Desktop session with the same user. In Windows Server 2008 this is not possible by default. If you login with the same user account the first session will be taken over by second session.
But you can allow multiple Remote Desktop sessions per user by changing a registry key.
Check out the follwoing registry key HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\TerminalServer
If the fSingleSessionPerUser value doesn’t exist, create a new DWORD value named fSingleSessionPerUser
Open the fSingleSessionPerUser value. The possible values for this setting are as follows: 0×0 Allow multiple sessions per user 0×1 Force each user to a single session
The pagefile size on Windows Server 2003 x86 and other Windows x86 platforms is limited to 4095 MB per pagefile. But a lot of Windows Server 2003 systems already have 4GB RAM and are using PAE (Physical Address Extension) to use them. So it would be useful to create more than 4 GB pagefiles.
Microsofts solution for this is to create multiple pagefiles. You can now create multiple pagefiles on different partitions. If you don’t have enough partitions or you just have one, you can create multiple pagefile in different folders by using the Windows Registry.
Create the folders on the drive where the pagefiles should be located. For example, C:\Pagefile1, C:\Pagefile2, and C:\Pagefile3.
I would recommend to create a backup of the registry
locate this key:
Edit the value “PagingFiles”
Remove the existing values and add the following values:
C:\Pagefile1\pagefile.sys 4096 4096
C:\Pagefile2\pagefile.sys 4096 4096
C:\Pagefile3\pagefile.sys 4096 4096
Note: It’s still recommended to have the Pagefiles on the same partition as the system
