I have 5 servers - 2 Windows 2003 and 3 Windows 2000. All have shares. All are peer to peer (No Directory Services or Domain). Until Monday, all servers could access all shares on all other servers. Due to some change we made in firewall or other activity (??), two of the WIndows 2000 servers cannot access one of the Windows 2003 shares. All XP clients can access all shares on 2000 and 2003 servers. All 2003 servers can access shares on 2000 servers. The 2000 servers can access the shares on 2003 server 1 but NOT on 2003 server 2. We made no known changes to permissions. However, we did install a new firewall appliance and were restricting some access. We have since backed out the firewall settings. It appears to be some permission issue. Message we get is "The network name is no longer available" or "The network services have not been started". Again, we can go from the 2003 server to the 2000 server with no problem but not the other way around.
