Local printing using terminal server 2003 suddenly stopped.
Windows 2003 Terminal Server was virtualized 60 days ago in preparation for move to new Windows 2008 R2 Terminal Server. Virtualized server has been working great but has suddenly stopped picking up default local printers of terminal server users when they login. No local printers are showing up as available printers (as sessions) in the print queue. This terminal server has been running flawlessly for three years and every user has had a local printer connected to their remote PC which has been working with the terminal server for those three years. Suddenly today - no local printing is working through the terminal server at all. The only thing that I noticed was that the registry DWORD value "FFFFFFFF" set for "FilterQueueType" (that I had originally modified to make printing work) was "missing" from the registry. I have know idea how that would have happened. I added it back in but no fix. Makes me wonder what else happened to the registry. Nothing else had been changed - really. How can I get local printing going again without having to restore virtualized server?
