have fixed the conflict on the 10.17.12.30 interface by removing ms networking, file and print sharing and netbios over tcpip. these shouldnt be there anyway since that interface is a pure tcpip to link to an internet router.

the conflict on 10.10.10.1 remains.

the ip in the 4319 event is the ip of server4. the multihomed 2k server.

just had that idea myself about 15mins ago. and it fixed it.

1. will I have to use lmhosts on machines on the vlan3?
2. should i disable vlan3 netbios on all the servers which are multihomed? (the server 4 is the 1st DC, we have 2 more)

Netman66Commented:
1)  Probably not.  If your DNS is functioning correctly there's a chance you won't need to use LMHOSTS or WINS.
2)  Only if they are experiencing the same conflict.  If not, they should be okay to leave as is.

re 2)

i can only see the problem reoccuring if another server decided to become the master browser or we took down  server4 for maintenance.

Netman66Commented:
You can prevent them from becoming the master browser via a registry hack:
