I'm running Windows 2003 Small Business OS on an application server and have no trouble running programs from the server on any of the client computers. There are only 4 client computers on this little network and we are licensed for 5. The problem is that we cannot use network neighborhood to access each others computers and this is something we would like to do. I'm not a total neophyte but Windows 2003 has me very baffled. Things worked last week just fine and we could all use the network. The LAN and server were turned off for the weekend and now we get connectivity errors. The clients are running XP Home. Nothing changed over the weekend except the ability to use the LAN. I read the other thread and tried turning of License Logging but that didn't help and I've rebooted the server to see if that was a problem. I repaired all the LAN connections and got no interesting messages. The router shows all IP address properly and there is no trouble with the WAN connection. Now what?
