Network Neighborhood Browsing problem

Hi all,

I have a simple problem and for the life of me, can’t find the answer to it.
I have some old and test domain/workgroup names showing in my network
neighborhood, which are not really there. I tried to restart my Wins servers
(deletemappings) and used browmon and can not find who is holding on to
these bogus entries. I have a suspicion that some master browser/backup
browser/browser is holding on to these entries and am trying to remove them.
I have multiple VLAN’s and a mixture of Win NT 4 and 2K workstations running
on my network. Anyone know of a utility out there that would clean out the
old names?

Thanks in advanced.

Mitch
