I have a server setup that has 3 nics. 2 are external, one is
internal. The two external have 2 different ip addresses 72.x.x.109
and 72.x.x.110, but the same subnet and gateway. The third uses a
private ip. The server is setup as a gateway computer. I am running
IIS and hosting 2 websites on one of the interfaces, as well as email.
The second interface hosts webmail for Kerio.

I am having an intermittent problem with the first external card. It
looses connection to the internet, without warning. No one can see in,
it can't see out. If I disable and re-enable the card, the problem
clears. I noticed that when I run a repair on the card, it throws up a
warning that it can't clear the arp cache, so I ran arp -a and noticed
that there was no entry for the 72.x.x.109 network card. the 72.x.x.
110 card is there, with its g/w specified, as well as the 192.x.x.x
card. When I disable and re-enable the 72.x.x.109 card, it shows back
up in arp -a with its g/w and all works fine for a couple days... I'm
at a loss, here. I have tried switching out the card, deleting it and
re-installing, but none of these solutions worked.

Any ideas would be greatly appreciated

Thanks
I might be wrong, but how can the external have a static IP on the same network? I would think one would have to be DHCP.
