*TIP*

If your home PC or office worstation needs to be on 24/7, give it a restart once a day to prevent crashes, loss of data and overall problems.

Ok, slightly more technical one for you guys....

2003 Server distributing DHCP to clients. A new default gateway is introduced to the DHCP settings (scope options not server options). The old default gateway is pushed down to be the secondary gateway.

All clients receive the settings but after five minutes, checking via ipconfig reveals that the clients have lost the setting of the new default gateway, and have reverted back to the old default gateway (now the secondary). Rebooting just replicates the problem, while a release/renew just starts the cycle again. Setting there, then not there.

There is only one DHCP server in the network.

Any ideas?

Background info... the office is in an area where adsl is not available, so we have satellite. This is very expensive. We are trialling unwired but because the signal is not that strong (reliable) we need all VPN traffic to run through the satellite, while all other traffic runs out of the unwired - hence the new default gateway.

Any thoughts?

Sounds to me like there may be something else on your network giving out DHCP settings, could that be a possibilty?

[Grant]

Officially there's only the one dhcp server, but I decided to sniff the network anyway. Didn't find anything though.

Very strange and very frustrating...

Are there maybe any login scripts (run from AD) that are running a batch file or command to modify your gateways using the 'route' command?

Just a guess, if you're sure there are no other dhcp offerers around. I know it's a bugger unplugging the dhcp server (which probably does other more important things as well) but you'll have to have done that (and I assume you have.)

hey all, anyone know where I can get a free program I can run that will tell me the computer's serial number?

[ZAP]

The only serial number is in the CPU, is that what you are after ?

[XRSICKT]

I dunno, if that's the only one then it must be what I'm after.

Try:

ipconfig /all

It will tell you the IP address of the DHCP that you received your IP address from.

How are you doing two "default" gateways? Obviously two defaults are impossible for the computer to understand. Are you defining routes for different Internet addresses via each gateway using the route commands?

Can you main gateway router handle the re-direct for your clients? What I mean is, have one router as the gateway for all clients and have it know which way to route the traffic.??

Why won't some PCs with winXPSP2 and good wireless network cards allow you to connect to the wireless router with 128bit encryption yet will have no problem with 64bit encryption. When comparing a working PC's settings to one that won't work I see no difference.
