Windows 2003 Srv - Losing Def Gateway

29 Jun 2009 11:42 PM

Nick Jax

I have a Windows 2003 Server (sp2) with 2 Broadcom Netxtreme Gigabit
Ethernet cards.

Both cards have their IP addresses (gateway, dns etc) statically assigned.

One of the cards loses it's default gateway periodically. If I run a
"repair" on the NIC, it comes back for awhile. I tried disabling "dead
gateway detection" but this has not resolved it.

Any suggestions would be appreciated!

With multiple NICs, only one should have a gateway, which is essentially 'the doorway out to the world.' If you need another gateway for whatever reason, you can create a static route in RRAS.

Curious, is this server a domain controller?

No this is not a domain controller.

The strange thing is, it has been working just fine for almost 2 years with
2 gateways. Why would it become a problem all of a sudden?

Thanks,

Don't know. Maybe it woke up with an update? It's pretty much been a defacto an a rule all goes by when setting up a machine with multiple interfaces that only one interface on a machine can have a gateway, which is the DEFAULT gateway to the 'world,' so to speak. How can something have more than one default gate?
