I have a home network using windows xp professional with 3 computers on the network. Up until the other day I have been able to share files and printers across all 3 computers. Suddenly I am no longer able to access files on the shared printer on one of the computers. I am able to access the other 2 computers from that computer and that computer can still access the internet on the network as well. But I can no longer access anything on that computer form the network. I have tried everything I can think of to figure this. There is no active firewall, sharing is turned on, etc. If anyone can help I would greatly appreciate it.
