I have a customer who has a Dell Server running Win 2003 R2 Server. This is an existing machine that we had setup with a static IP. Now they want to change it to another static IP.

When they go and change it, hit ok, then reboot. The config is back to the old IP #.

The user is the administrator.

My guess is it has to do with AD & GP, a virus, an already in use IP#, or something else?

Anyone have any ideas what else could cause this behavior?

Not sure why this is tagged with DHCP, it sounds like both addresses in question are static. Did I miss something? – MDMarra Sep 8 '09 at 23:15
Most servers have at least 2 NICs, are they definitely setting the new address on the right one? – MDMarra Sep 8 '09 at 23:16
I had tagged it DHCP by mistake, cann't remove it now – shaiss Sep 9 '09 at 0:25

I had a similar problem on a Dell PowerEdge 1950 with Broadcom NIC's installed. Running "netsh reset int ip" from a command line fixed it.

Does it work after changing the IP, before rebooting? Rebooting is not required to change an IP address.

Is there any anti-virus or security software that may be overzealous in protecting network settings?

Broadcom NICs? Its a known issue. I can't remember the solution exactly, but if you call Dell support, they should be able to help you in a few minutes.

Basically this is due to a package not installed properly during Dell automated install (or maybe vice versa - you HAVE to use the OMSA CD to install the OS)

Just call support - it's a well documented issue, easy to solve

still looking in to this. Our user is going through upgrading their nics. We'll see if that helps at all, then I'll mark this as answered. Thank you – shaiss Sep 16 '09 at 20:44
This is why we don't use the broadcom NICs, we always get Intel NIC cards to save us any trouble. – Hondalex Nov 2 '09 at 17:04
Hondalex, b-coms are OK when you know their quirks, and this issue has been around for years now - there's an easy and well documented solution available, only one support call to Dell away – dyasny Nov 3 '09 at 10:21
