We have a customer who has a mixed 2000, NT and Netware environment. The main server we will call T1 is a DC setup with DNS, DHCP, WINS. All clients are mixed 95 and 2000 can connect to T1 and the other 2000 member servers. The 2000 member servers can connect to T1. The DC, T1, can see the other servers in network places. When you try to open up the server you get an error 'network address is invalid'. You can however open up the NT server and Novell server with no problems. If you try using 'Net Use' from T1 you get the same error. Only going into explorer will allow you to map a drive. The problem was noticed, not being able to open this up in network places is that for installing Symantec AV to other servers and adding resources to Veritas backup it needs to connect to the Admin$ on the other servers. Doing a map to Admin$ works but you still get invalid network address in explorer, NAV or Veritas. There was one article on Vertitas that said if you are using the Novell client, which T1 is, to set the provider order to Microsoft first, Netware second. Made that change and still have the same problem and error. Any direction would be appreciated.
