CITRIX ERRORS

I am running a Citrix metaframe (1.8 sp3) over NT terminal server(sp5). Every time dr watson reports an error with spoolss.exe all remote users connected to this server are thrown out but they can work again once i restart the spooler service.

When i check the event viewer, the following error is registered;
Event ID: 1000, Source CLTMGR “the server was not able to initialize the client management virtual driver (error 13)”

I really dont know how these two errors are related but beleive me i am in really hot soup. I have tried the solution on citrix.com (CTX395746) but it doesnt work.

please help !!!
