We have mostly Win2K Pro sp4 clients with NT4 sp6 as DCs.
Network Neighbourhood is very slow, probably about 45 second to show the computers in the domain.
also, enumerating files in a 'save as' folder drop down dialog also takes much longer then it used to.
The only thing which has changed (that I can think of) is, we installed a 'TEST' domain for some tests we were doing.
This domain is gone now though.
Our WINS runs on 2 win2k servers.
Any ideas ?
