What does this mean?

Suddenly,....It was gone.....!
My networked printer, that was running fine, just decided to turn grey (the icon, that is) and say in blood red letters:
User Intervention Required
Use Printer Offline
The printer works well from the attached xp machine but not from the networked 95 machines
Did all the troubleshooting suggested in other threads and the pinging of ip addresses and computer names works fine.

Please, there has to be something I am missing

 

XP didn't just apply service pack 2 did it? The Automatically applied firewall could certainly cause issues for file/printer sharing...

None of the nodes on this LAN are connected to the internet.
Thanks for troubleshooting with me, though.

 

The XP server has no Internet connectivity? So, you are saying that an automatic update is impossible?

Something happened that turned on filtering of some sort. Or printer sharing should still work just fine. Things don't just break spontaneously without something changing either automatically or by hand. XP's auto update recently including the new firewall that is turned on automatically is just one of the more likely scenarios.
