PROBLEM STATEMENT
------------------------
We use Remote Desktop client connection to remotely administer our servers. Any Remote Desktop client connection to Windows Server 2008 R2 Remote Desktop Services disconnects at random intervals with the following error message:
*
"Your Remote Desktop session has ended. Your network administrator might have ended the connection. Try connecting again, or contact technical support for assistance."
*
This disconnect issue is only a problem on our 2008 R2 64bit servers; our 2003 SP2 and 2008 SP2 32bit servers work fine.

ATTEMPTED FIXES
------------------------
I searched internet KB's and only found the following two possible fixes that recommended changes to the local server policies:
*
Fix #1: Run gpedit.msc, then navigate to Computer Configuration\Administrative Templates\Windows Components\Remote Desktop Services\Remote Desktop Session Host\Remote Session Environment\Set compression algorithm for RDP data, select Enabled and choose
Balances memory and network bandwidth.

Fix #2: Run gpedit.msc, then navigate to Computer Configuration\Administrative Templates\Windows Components\Remote Desktop Services\Remote Desktop Session Host\Connections\Configure keep-alive connection interval, select Enabled and set Keep-Alive interval
to 2.

I applied both of the changes, but they did not resolve the problem.

RUNTIME ENVIRONMENT
------------------------
1. All servers are in a AD domain and have the latest service packs and updates.
2. All XP and Windows 7 client workstations are in a AD domain and have the latest service packs and updates.
3. We remotely administer our servers from Windows 7 workstations that have the most recent version of the Remote Desktop Connection client installed on them.
4. The 2008 R2 servers are all Dell PowerEdge hardware with the 64bit Standard edition OS.
5. The 2008 R2 servers all use the "Remote Desktop for Administration" Licensing Mode (they do not have the Remote Desktop Services role installed).
