Cannot Modify IP Settings

I have a Windows 2000 box where an administrator logged into the box cannot
modify any settings on the Advanced TCP/IP Settings dialog of the active
network adapter. You make changes and hit OK to save, but as soon as you
re-enter all of your changes are lost and the same initial settings are in
place. Some things I tried to change included adding DNS suffixes,
disabling NetBIOS over TCP on the WINS tab, etc.

I assume some security setting has done this? What would prevent even an
administrator from being able to change values on the tabs of this dialog?

If this is a domain computer logon as the local administrator - not a domain
account in case there are domain level Group Policy settings that may be
causing the problem from user configuration but usually the user would just
get an access denied message. Try running the command ipconfig /all and the
support tool netdiag to see if anything unusual is found and also see if
there are any pertinent events recorded in the system logs of the computer
as shown in Event Viewer. You may also want to try reinstalling tcp/ip on
the computer to see if that makes a difference though that would probably
make the computer get it's IP configuration via DHCP initially so you would
want to jot down any static IP address if one is used in case you need to
reconfigure to static IP. Booting into safe mode with networking may also
be worth a try in case some "protection" software on the computer is
stopping changes from happening. Many malware/spyware/firewall programs are
locking down a lot of computer configuration with or without the computer
users knowledge. --- Steve

W2k allowed very little to be delivered to it for network interface config
from group policy, but the mechanism could be harnessed to directly
zap values in the registry (but that would not give the immediate reset
you are seeing).
Sounds like some sort of system sickness/malware may be at work.

Is this Win 2000 server DC or is it just domain server?
Looking for errors in event viewer and report here "event id" and "source".

This is a member server. No errors in event viewer corresponding to
network settings or at the time of the event.
