Servers Losing NetBios Connectivity

[Guest Bencairney]

Hello,

 

I have an NT4 domain with primarily Windows 2003 Member servers, in the last

few days we have experienced several issues with loss of Netbios connectivity

on some servers.

 

The first issue seemed to be related to the browse list. Servers on one

VLAN disappeared from the domain browse list and could not contact a master

or backup browser.

Rebooting the server acting which they thought was the master browser

resolved the issue and the servers all appeared in the browse list again.

 

The second issue occured with one server, it was still available in the

browse list but could not be connected to via netbios. Net view command

generated a system error 64. The server was rebooted to resolve. No errors

were written to the event log and the server could be connected to over

remote desktop and pinged successfully.

 

I'm not sure where to go from here with this one as the lack of errors in

the eventlog make it difficult to diagnose. WINS runs on the NT4 domain

controllers and seems to be functioning.

 

Has anyone expereienced a similar issue?

Thanks. Ben Cairns
