W2K3 Server with 2 NICs

I have a problem with my W2K3 Sp1. It's web server, first nic has a site in
internet and second in intranet, both on their own subnets. Internet site is
straight behind FW and intranet is in its own vlan, which has also two AD
domain controllers. Server is a member in AD domain for user authentication
in intranet..

First nic (Internet):
ip 194.100.100.101
mask 255.255.255.240
gw 194.100.100.1

Second nic (Intranet):
ip 193.100.100.101
mask 255.255.255.248
no gw address, because server gave warning about multiple default gateways.
(subnets gw address is 193.100.100.1)

Problem is, that users can't connect to intranet, they get "site not
available...". Intranet's nic doesn't answer to ping. Earlier when both nics
were in same subnet everything worked fine. I've got information that
problem could be solved using route command. Is it possible and if it is,
what would be right command?

If all of the intranet users are on the same 193.100.100.0/255.255.255.248
subnet as the 193.100.100.101 NIC, then this is not a routing issue. Try:

Right click My Network Places and select Properties. Click
Advanced/Advanced settings and make sure the Local Area Connection for the
intranet NIC is at the top of the binding order.

If however, there are clients on other subnets and the gateway to those
subnets is 193.100.100.1, you have multiple problems:

1. The 193.100.100.101 NIC has no route to the other subnets.

2. 193.100.100.101 cannot use the 193.100.100.1 gateway because the
addresses are not on the same subnet.

Thanks for quick answering!

There was a little mistake in my first message, the gw address is
193.100.100.100 and so it is in th same subnet as Intranet nic. In this
subnet is also another web server (wsus) and clients have no problem
connecting it from other subnets. The setup in vlan is same (allowing http,
https all) for both wsus and intranet's addresses. First I tried to put the
gateway address in Intranet nic but it didn't work and server warned about
this kind of multiple gateways configuration. In microsoft kb articles they
recommend using static route for solution. I tried all kind of route
commands but nothing worked.

Assuming that the 193.100.100.100 gateway can reach these other subnets,
then for each such subnet you would run the following command on the server:

route -p add <IPofRemoteNetwork> mask <subnet mask of remote network>
193.100.100.100.

For example, to reach a 192.168.1.x subnet you would run this command on the
server:

route -p add 192.168.1.0 mask 255.255.255.0 193.100.100.100.
