We're having problems with a peer to peer network that was working but now isn't. We don't use the peer to peer often, so I don't know when it stopped working. 3 computers have XP pro. 1 has 2K Advanced Server. On the 2K server I can see the other computers but get the message "not accessible" "The network path was not found". On one of the XP Pro machines (I havn't checked the others) only itself is visible. We are using a linksys router (which is a recent replacement due to some bad ports on the old one). I'm stumped on how to trouble shoot. We are sharing files and folders, have Client for Microsoft Networks, File and Printer Sharing and TCP/IP..... Any help is appreciated.
