All of a sudden Windows does not recognise the server or netwoekd printers anymore. Our MACs have no problem seeing the server/printers. It worked fine for a while. I did a system restore, but that resulted in my entire system to lock up and I had only a black screen. When I undid the system restore, everything worked for a couple of days fine. But now the same problem started again. Windows does see a networked scanner but the printers appear off-line and the server does not connect.
