I have a server 2003 box with dual nics for Websense.  Websense requires one NIC for monitoring and one for blocking.  I have them both on the same subnet with different IP's and everything else the same (GW, DNS).  What's happening is I can access all shares and RDP to the server, but I can't ping my gateway or any other hosts on my local network (nor can I ping the outside world).  DNS is working because I can try to ping internal and it will pick up the IP but not be able to ping the host.  Any suggestions?

You should only provide default gateway for one of the NIC's.
If you give both of the nic's a gateway address, I think that
your network infrastructure on the machine will not work.

Ok, I figured this one out, just had to read the instructions better.  The second NIC needed to be in promiscuous mode to make this work.  All I had to do was unbind TCP/IP from the NIC and now all is well.  I was confused as to why/how they wanted two NIC's on the same network, that just makes a routing mess!!!!
