Recently a new workgroup name appeared in our organizations "Network
Neighborhood > Microsoft Windows Network" The workgroup or domain is
called "Gotcha." Not a particularly pleasing name for a workgroup.

Having verified that no staff members have plugged in new hardware recently,
and verifying that there are no unauthorized logins to our wireless network,
I'm somewhat at a loss to explain this. I found information on an SMB hack
that, as a side-effect causes a rogue workgroup to show up in Network
Neighborhood in order to sniff cleartext passwords from Windows 95 machines,
but our firewall blocks ports 137 and 139, and there's nothing unusual in the
firewall logs.

My question is this--what's the best way to track down an IP address
associated with a domain or workgroup listing in Network Neighborhood. Is this
possible? This would at least give me an idea of where on the physical network
this is coming from. Does anyone have recommendations on tracing this problem?

Thank you,

Gary
