Win2K Server - problem with running two NICs on two subnets on one machine

Hi,

We're running several operational applications on 4 Windows 2000 Server machines.  We recently attempted to set up a separate network to run backups over (installed second NIC cards, enabled the 2nd network in Network Settings, assigned the second IP and assigned the Gateway as it's own IP (e.g. Network 1: IP: 1.2.1.1, Def. GW: 1.2.1.1; Network 2: IP: 1.2.2.1, Def GW: 1.2.2.1).  We connected everything up to the switch and both networks were running, doing their thing.  However we started experiencing problems with our operational clients accessing the applications on the server (over the 1st network) since enabling the second (backup) network.  Eventually the clients stop being able to access the server.  The applications continue to run, but the connection dies.  We rebooted the server and the connection would come back up.  When we disable the 2nd network, the connection is fine and doesn't experience problems.  At one point our backup/restore server (what the 2nd network is connected to) was completely down and shut off, so there was a period of time when there was no (or minimal) traffic over the 2nd network, and we still experienced problems over the 1st network, with both cards enabled.

has anyone seen anything like this?  Is there something else we need to configure?  Unlike UNIX, for Windows both networks have the same computer name (in UNIX we assigned each NIC it's own hostname).

Thanks much

Leave the default gateway on your "backup network" empty.
