winlogon.exe - Application Error on Citrix Session

I have users in Citrix that get the following error when they login to their Published Applications on Citrix Servers. The Servers are W2k w/SP4 and all of the Lates patches, Citrix XP 1.0, with SP4, and a few Hot Fixes.

winlogon.exe - Application Error
The instruction at "0X10017ef4" referenced memory at "0X01ca8000". The memory could not be "read".
Click on OK to terminate the program
Click on CANCEL to debug the program

When they click OK or Cancel their published app closes out.  Any ideas?

I have seen this before in that config. You need to get a MS supplied hotfix (MS will supply on request. It is not available online) and install this on the server and the clients.
Not sure of the hotfix details but I found it quite easily on MS website.

Hope this helps
