Do you get the same problem when you connect to the Citrix server
with an rdp client in stead of an ica client?

When this problem occurs, how is CPU and memory use (in Task
Manager on the Citrix server)? Any processes that monopolize the
CPU?

Since you seem to be able to repeat the problem at will by opening
a document from within Word, have you tried to monitor the system
with Performance Monitor and Network Monitor when the problem
occurs?

Does the problem also occur when you doubleclick on a Word
document to open it? Does it happen with *any* application, also
notepad? What is the default search path for the Open document
dialog in Word?

You write that you "applied all the patches" to the servers. But
since you are still on SP3, I find that hard to believe. Do you
really mean that you applied *all* patches that were contained in
SP4 *as separate hotfixes* + *all post-SP4 hotfixes*???
Reason why I ask is that there are numerous performance problems
solved in SP4 and post-SP4 hotfixes. I can't really list them all,
it would be easier if you listed the hotfixes you have installed.

Which version of Citrix are you running?
