I'm running Server 2003 web edition on a server with 2 nics, in a datacenter
where I have 2 IPs allocated on the same subnet with the same default gateway
address. Each Nic is assigned it's own IP address - all other network parms
are set up the same on both nics (DNS / Default Gateway).
After a few days, I started getting random connection loss on one Nic at a
time - never both. In some cases, the connection will restore itself, then
the other nic might go down - or possibly the same one again. Seemingly
random. Disabling & re-Enabling the Nic brings it back online - for a while
After searching for a while, I discovered another symptom - when I lose my
connection, if I do an ipconfig /all, the disconnected Nic shows a blank
I have read all the posts about how having 2 default gateways is not
recommended, and it is probably at the root of the problem here - what I
haven't found is a clear explaination of how to work around it.
If I remove the default gateway from one of the Nics, everything seems
stable, but I can't access the services on that Nic's IP. It seems the only
way I can have separate services running on different IPs, each assigned to a
different Nic, is with a default gateway entered for each one (the default
gateway is the same address on both Nics). But this clearly is causing a
Any advice on how to work around this is appreciated.
