Win2003 SP1 as DC with 2 NICs for domain

Hi everyone!

I have problem with with second NIC on Windows 2003 SP working as domain
controller.
I have two subnets: 192.168.40.x and 192.168.125.x,
Each NIC is dedicated to one subnet.
First one is working excelent and this subnet is able to use domain.
Second one is unable to use domain, NIC is working correctly but computers
on this subnet don't see DC and I cannot use domain security on this subnet.

Anyone has solution or at least to point me where to dig for solution?

Regards

Hrast

Having a multihomed DC is a recipe for disaster. Just use on NIC in the
DC and use some other device to route between the subnets.

Should I create additional DC on other subnet or just route the subnet
thruogh router?

It really depends on what you are trying to do. Two DCs is always a
better setup than one. But one DC serving two subnets is fine (as long as
the DC is not doing the routing itself).
