Multihoming recent bug

[Luke Richey]

So far nobody has been able to figure this out. I am the
4th person in this newsgroup in the last 3 days who has
noticed that this behaviour has just recently started
happening and it is not limited to Windows 2000. C'mon MS
figure this out!!

This is started happening about 2 weeks ago for no reason.

We have 9 Windows 2000 Multihomed Servers (At several
locations) with all the latest patches, they are very
different in their configurations but for some reason all
three randomly will drop the static settings for one of
the network adapters (sometimes the same adapter
sometimes not) and there is no specific amount of time
until they do this, sometimes it is every 5 minutes,
sometimes every day.

This just started happening, after it happens one of the
NICS then has a 169.x.x.x IP address and a release and
renew on the DHCP based one will not work. We have to
manually reset the settings and then reboot! Then it will
only work for awhile.

We have tried installing different brands of NICS from
3COM, Intel and Linksys with old drivers and new drivers
with the same results

Each machine has virus packages that report clean (Three
different AV packages)

We tried DELETING the CONFIG area for the
HKLM\System\CurrentControlSet\Control\Network with no
luck after reboot. As soon as we reconfigured the NIC
with it's static IP the same problem started occuring.

I think I can safely assume:
1) This is not a driver problem
2) This is not a virus
3) The OS has a recent bug from some patch?

Example Systems

BUILDING 2, NETWORK 2

SERVER B
NIC 1 - Static 10.0.0.2
NIC 2 - 9 Static External IP Addresses

SERVER C
NIC 1 - Static 10.0.0.3
NIC 2 - Static External IP Address

BUILDING 1, NETWORK 1

SERVER A
NIC 1 - Static 10.0.0.2
NIC 2 - DHCP from Cable Modem

SERVER D
NIC 1 - Static 10.0.0.4
NIC 2 - Static External IP Address

SERVER E
NIC 1 - Static 10.0.0.5
NIC 2 - Static External IP Address

Any Ideas?

My only suggestion would be to uninstall TCP/IP on the systems and reinstall. 285034 How to Remove and Reinstall TCP/IP for
Windows 2000 http://support.microsoft.com/?id=285034. If that doesn't work, I would strongly suggest you call Microsoft Support
and open an incident at your earliest convenience.

Thank you,
