Setup Subnett, Dns issue, unable to see cloud? 1

[paulm22]

Setup a subnett at a different physical location, I can ping all routers and the computers entered in the routing setup at the new site using ip helper(Cisco Routers). I'm wondering if I need to configure a new secondary DNS zone with the new subnet address using the same DNS Server?

If I understand you properly, you've got a new subnet, and you're not picking up an address from the DHCP server.

Things that I can think of that you should do include:
1. The routers need to have an 'ip helper-address <DHCP server address>' statement to forward the DHCP-discover broadcast (You said you've done this)

2. Set up a new reverse-lookup zone for the new subnet on your DNS server.

3. Configure and activate a new scope on the DHCP server for the new subnet.

If this does not work, you may want to sniff out some packets and filter for DHCP.

If I'm overlooking anything, please someone let me know.
