I have a Win2k8 R2 server and Win 7 clients. The Server has DHCP and DNS running on it. So far so good everything works fine.
Now the problem comes when I also enable DHCP on the router so that clients can get an Internet connection when the Server is down. This is on the same subnet but a different IP range.
If the clients happen to pick up their IP from the server then all is fine but if they get it from the router's DHCP then the DNS record on the server does not get updated even though dynamic updates is set to 'nonsecure and secure'. Is there anyway I can have both DHCP sources and still update DNS on the server when it is available?
