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?
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
