New (additional) DHCP scope won't hand out leases

I have added a 2nd DHCP scope to our existing Windows 2000 DHCP server so that the current production scope can be disabled (we are moving to a different IP range with more host addresses).  When I disable the currently running scope and enable the new one, none of the DHCP clients are able to get a new lease.

Thanks for the quick responses.  I will try to answer all the questions in this posting.

I made no changes to the router although my office network is completely flat (no vlans or other segmentation) and the DHCP server already hosts a scope that is handing out leases properly.

The DHCP server is on the same subnets as the clients (again, the network here in the office is flat). The lease length for the current scope is 7 days but I did try to release and renew DHCP on a test client and the request times out.

Thanks!

Hi,

why dont you just delete the old scope and create the new one. all devices that have the old ip will keep working and the new one will get the new leases. ofcourse, your router interface should have secondary ip from the new scope.

regards,
I was finally able to get it working.  I changed the IP to an address in the new subnet and after a reboot it began to hand out leases properly.  

Netnounours, I did try adding a second IP address to the existing NIC and it did not help.  Just so you know.

Thanks everyone for their help!
