I have a Windows Server 2003 Enterprise Edition SP2 (not R2) box running ISA 2006 Enterprise Edition.

I am trying to RDP this box, but I am unsuccessful.

Just so people don't blithely post a "solution" and then leave, I have:

-Rebooted the machine
-Checked the registry to make sure RDP is truly enabled
-Turned RDP off and then on again
-Checked my ISA rules to make sure the computers I am RDPing from can connect to the ISA server in general
-Confirmed the immediately aforementioned by pinging the ISA server
-Tried RDPing from multiple machines running various OSes (and therefore various versions of the RDP client) (without success in all cases)
-Tried RDPing the ISA from the ISA itself using 127.0.0.1 (loopback) as the destination IP (without success)
-Disabled Offloading and RSS<br/>
-Confirmed that the ISA server can access the machine I'm trying to RDP it from (by pinging it)

Also worth pointing out, the ISA server functions and has no other problems other than being unable to be RDP'd.

For clarity, I get this error when I try and RDP it (in all cases).



I can use GenControls to VNC the ISA server in question (this is not a solution).

I have a second ISA server that is setup similarly (I believe I followed all the same steps setting them both up (did them both one after another last night)) with the exception of connection-specific publishing rules...it can be RDP'd.

Also, I used WireShark to confirm that the ISA server is indeed receiving the RDP requests etc. from the machine I'm trying to RDP it from -- it is.

Thanks for any/all help you may be able to provide.
