Problem with two NIC's in one server
Posted on 2009-04-09
I have a server running Server2003 with IIS and Citrix Secure Gateway. It has a dual NIC. One NIC is configured with the IP of our Citrix web access page . The other is configured with the IP for the secure gateway. Both NIC's are configured with the same subnet, and default gateway. When I close the tcp-ip properties on either NIC, Windows gives this warning.
Multiple default gateways are intended to provide redundancy to a single network (internet/intranet). They will not function properly when the gateways are on two separate disjoint networks such as one on your intranet and one on the Internet. Do you want to save this configuration?"
I chose yes and everything seemed fine. After a while the web page became unavailable. Disabling and enabling or repairing the connection on the NIC's fixes the problem temporarily.
I have read that you cant have two NIC's in the same server on the same subnet.
