Terminal Services Service fails with error 7031.

[Andrew Brazier]

We get this error on a Citrix server, when you boot the
server it takes a long time to login, several minutes and
then you get and Event ID 7031 Terminal Server Service
failure, and an Eent ID 26, Termsrvr.exe Application Error
exception possible deadlock condition. This totally kills
the server, Citrix won't run at all. uninstalling Terminal
Services restores performance but of course makes the
server useless, reinstalling TS brings the problem back
again. Server is Win2000 SP3, Citrix is Meaframe XP FR3.

Any ideas/suggestions?

This problem is fixed in SP4. Any specific reasons why you haven't
installed SP4 before? There were some logon issues with SP4 and
Citrix, but they have all been solved a long time ago.

Thanks for the reply, we're running SP3 plus hotfixes
(some recently provided by MS tech support and applied to
address a profile issue) and checking the version of the
files referred to in Q324443 they are older than those
presently installed. Will SP4 definitely cure the problem?
Mind you, we're just about at the point of having nothing
to lose?!?!

Well, I can't vouch for it (that SP4 will solve the problem), but
KB 324443 says so. Since you have installed SP3 + some pre-SP5
hotfixes, you might have only part of the solution that was
implemented in SP4.

Since you don't have anything to lose, I would make a complete
backup of the server (including system state) and install SP4 +
re-install any pre-SP5 hotfixes.

As you said, nothing to lose! I applied SP4 to the failing
servers and it seems to have done the trick! They now
reboot and all services start normally. I will give it 24
hours before I start cheering though!

Thanks for your suggestions.
