Does your router also give out DHCP addresses? If so you'll want to turn that off.

When you look at the connection properties, does it list your server as the DHCP server?

You have another DHCP server on the network handing out IP's. You must disable this! refer to your router manual on how to do this.

Run an ipconfig /all on a client. Look for the line:

DHCP Server . . . . . . . . . . . : 191.168.1.x

If the IP in there is different to your windows DHCP server, then hunt it down & eliminate it.

my router DHCP is off, and now when i see ipconfig my DHCP server is : my router ip ? – air Mar 7 '10 at 12:08
Does the router need a reboot for that config change to take effect? Might be worth it, just because. – Ben Pilbrow Mar 7 '10 at 12:55
