I have several dozen XPSP2 computers and 4 XPSP1 computers receiving DHCP
setup
from a DHCP server. I added an extra default gateway to be sent to the
machines to point to a another stanaldone server that has simple LAN routing
between the main network and a smaller network of about 5 machines. The two
gateways are 172.18.6.1 (main out to world) and 172.18.6.50 (the stand alone
server address). I moved the .50 address as the first resoultion gateway,
then the .1 for the second. I reboot the machine, ipconfig ALL it, and see
the
two gateways. Great. After some short random time, after accessing files on
the network and normal network stuff. The .50 gateway DISAPPEARS. ipconfig
doesn't show it, and netsh diag show gateway has it gone to. The computers
registry settings for the adapter interface still show the 2 gateways in the
keys but ipcong says the gateway is gone. I thought the DHCP server was
doing something flaky, so I shut it off. Turned Firewall off.. Still
happens. The XPSP1 computers
DO NOT do this. I even unstalled the Microsoft QOS service from the network
properties. It appears all the XP2 boxes do this after some short time.
IPCONFIG /RENEW fixes it back to normal with the same IP / gateways, but a
couple of minutes later it happens again. For now I have set a script to run
every 3 minutes to ipconfig renew, but this is crazy. The DHCP logs show no
changes. The system event log / app log / security show nothing when this
happens. Doing a route print shows the .1 gateway is the new default after
this happens, although the .50 still shows up in the routing table. A
sniffer shows no DHCP request changes. Any ideas. This makes no sense.. I
haven't seen this problem since the win 95 days. I hate to go back to SP1
