OK guys,
The client has multiple Windows 2003 Servers that are unable to connect via UNC to multiple Windows 2000 Servers in the same domain. I have been trying to isolate the problem using 4 servers. 2 of them Windows 2000 and 2 Windows 2003. All 4 of these servers are at the same data center. All servers have only ONE active NIC and only one IP address. All have correct reverse DNS and are static IP.
Here is the sample list, masked with some X's to protect client identity and sensitive information.
EXXB35 - 2003 - XX.207.42.198
EXX581 - 2003 - XX.207.42.19
EXX581 - 2000 - XX.207.42.18
EXX2DC - 2000 - XX.207.42.145
EXX2DC and EXX581 can net view or net use any of the other 3 servers without error. EXX581 and EXX581 are in the same physical rack, directly next to each other. All 4 servers run 100Mbit full duplex and get sub 1ms pings to each other.
From EXXB35 or EXX582 if you do a "NET VIEW \\EXX581" you will get the following error:
System error 53 has occurred.
The network path was not found.
Same result with IP or hostname. Same error with any valid NET USE command. I do NOT get the error from an XP workstation or from other 2000 servers.
From EXXB35 or EX582 I can do a "nbtstat" with "-a EXX581" or "-A xx.207.42.18" and get a correct response. Also a ping -a xx.207.42.18 will resolve to the correct server name. All 4 servers are in the same Organizational Unit within Active Directory.
All systems passed all netdiag tests. I have cleared the DNS and Netbios name cache's from all servers without a change.
From EXXB35 I performed "NET USE \\EXX581\IPC$ /user:domain\myadminacct" and get an error:
System error 67 has occurred.
The network name cannot be found.
All 4 servers can see \\domain\sysvol\ just fine. All have valid secure channels, three to the same domain controller at the same site. I have tried resetting secure channels and moving server secure channels to other domain controllers.
All the obvious problems have been checked, and many not-so-obvious ones. Any tips for what else to look at would be greatly appreciated.
Thanks,
Nathan
