Netbios traffic

System

My network admin thinks that Teamsite is trying to resolve a bunch of names on our network using the NetBios NameService. He shut down all the Teamsite services on the server and the traffic stopped. Anyone else have an issue like this? If so, anyway to solve it.

Domain list in dropdown at login has the servername and the domain only.

Environment -
Windows 2000 SP 4
Interwoven TeamSite 6.5.0 Service Pack 2
