I have a terminal server that during a print session will lock up. When I go to shut down, the message "oleMainThreadWndName" shows up several times and I need to end task to continue. Is this one of M.S. wonderful generic messages. The printer is an HP DJ connected to an JetDirectEx 300 printing at a remote location via tcp/ip (dedicated intranet). This issue only seems to happen with the inkjet printer at random times. All other printers setup this way don't seem to have any problems. The hp940 has recently replaced a hp952 that had the same problems. The error shows up in while in a terminal session.
