0 is not a valid handle

Guest

Hello,
I have a windows forms app built with vb.net, framework v. .1.1, sql server
2k5 backend, and uses crystal reports for .net. The app runs on a terminal
server with no more than five users. The problem is about once every other
day, when one of the users tries to print a report they receive a message box
with the error '0 is not a valid handle' Once this happens the server must
be restarted, because everyone else will receive the same error until the
server is restarted. Any ideas or help on how to track this down is really
appreciated.

TIA
