    I've got a Server 2003 box that I can no longer RDP to, but can access the registry, services, etc. of.

    This is a Citrix server that is having performance issues so I've been making changes to the settings with the goal of no longer neededing a weekly reboot. I recently made three changes, none of which should have disabled RDP.

    Here's what I changed:

    • Followed the directions in Microsoft KB 935649 to configure the PoolUsageMaximum and PagedPoolSize
    • Followed the directions in Microsoft KB823586 to disable speech and handwriting recognition
    • Followed the recommendation on this eventid.net page to set MaxWorkItems, MaxRawWorkItems, MaxFreeConnections, and MinFreeConnections under lanman paramters

    Now, when I try to RDP from Windows, I get a generic error that says remote access isn't enabled, the server is off, or not available on the network. After making the changes, we rebooted the server. When I connect using Remote Desktop Connection Manager, it says "unable to establish a connection" and a colleauge using mRemote gets a message about a socket error.

    Since we couldn't RDP, I removed the lanman keys and rebooted again, but that didn't help. I have also verified that the terminal services service, is started. Finally, I verified that the value of HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Terminal Server\fDenyTSConnections is "0".

    How do I resolve this further? Thanks.

    Citrix connections are working. Also, I don't believe this is an x64 server (I'll check though).

    I got into the server at the console and opened System Properties -> Remote tab -> removed check for "allow rdp" -> Apply -> add check for "allow rdp" and I can RDP again.
