We followed the steps given in more information
link(http://support.microsoft.com/kb/323497/en-us) but that didn't help
resolve this issue. Can someone direct us to a resolution?

Here are details of our environment:

Terminal Server : Windows XP sp2
Terminal Services client : Custom client based on rdesktop port to windows.
Terminal Services client runs on the same machine as the server. i.e.,
client connects to server over localhost:3389
RDP protocol version we use: 5
Encryption strength: 128

Thanks in advance,
Konda
 
Did I understand correctly that you are _not_ using the RDP client
from Microsoft? If that is the case I stronly suggest you try the MS
client to see if that fixes the problem.

I have not heard of this error before. At first I thought of
networking problems, but an incompatible client sounds like a much
better explanation.

I hope this helps.

You cannot connect to localhost on XP, at least not with mstsc.
I doubt that it's possible with just another rdp client, since XP
only allows one session at a time, so I suspect that there's more
non-standard configuration done on this machine.

We are using a custom RDP client, which is windows port of rdesktop. The
client connects to localhost. It works flawlessly but at times its
connection to MSTS gets lost. Is there a way to get more information on this
error? Does MSTS have any 'verbose' logging mode that we can turn on to get
more information?
