systemtray.exe error message on 2003 terminal server

Tech-Archive recommends: Fix windows errors by optimizing your registry

I am experiencing a strange occurrence on a 2003 x64 terminal server.
Whenever users create a new session, they always receive an error
message about a systray.exe application error. The message line is:
"The exception unknown software exception (xc0000005)occurred in the
application at location 0x00411a60.

I can't seem to find much info on this error. It doesn't appear to be
causing any problems, but it is a bit of a nuissance to our users. Any
ideas?
