We've got an NT4 controlled (1 PDC, 1 BDC, name resolution via broadcast) domain with other Windows 2000 Server and Professional workstations which have been working happily for years. This week I've had two system wide failures which I've traced to computers deciding they are master browsers and returning the *broadcast* address for the network (e.g. 192.168.0.255) when queried for the DC.
Fortunately I've got a Samba server on the network which has given me more detailed logging of the problem. It reports that two computers respond to its request for domain info and the invalid information (i.e. the broadcast address) gets returned first in most cases.
Has any body encountered this or could shed any light on the cause?
My tests suggest the bad master browser is running on the XP Pro-laptop of a visitor to the organization, but even if that's the source, what's the cause?
Advice and assistance gratefully received,
