Server does not find domain after reboot with dual NIC cards

[Guest]

I have several Win2k servers that have dual NIC's. On
NIC, sits in an isolated VLAN. The other NIC is on our
main network that has a DC. After a reboot, the machines
cannot find the DC. I currently fix this problem by
disabling the NIC on the isolated VLAN and re-enabling
it. The server then immediately finds the DC. Can anyone
help me?

You need to change the connection order for the adapters. In the network
connections window, click on the Advanced menu>>Advanced Settings. Make
sure the domain nic is at the top of the list.

It sounds like a network misconfiguration since disabling the card makes
the problem go away.

Without seeing your network configuration, it's hard to say, but a couple
possible causes come immediately to mind.
Default Gateways: Make sure you only have 1 DG on 1 NIC. The VLAN card
should not have a DG at all.
Subnet configuation: Make sure that the subnet for each network card is
different. If they are in the same subnet, you could run into problems.
With both cards turned on after a reboot, do a "route -print" to see where
traffic is being directed for the IP subnet that your DC's sit on.

Thanks,

Taking out the DG on the VLAN card did the trick!
