Way to test dhcp?

[pgaliardo]

We just switched circuits from frame-relay to ppp to one of our remote offices. We also switched routers - both Cisco 1721. We have a connection, but clients can't seem to get an ip address through DHCP. DHCP is given out through a Windows 2000 Server in the corporate office. We have a similar setup to another facility and DHCP works fine. I should point out that the remote office that works fine was a new setup from scratch. This one that is not working was an existing office and exisiting DHCP scope.

I have the ip helper configured on the Ethernet adapter. I am trying to determine where we are dropping DHCP packets. Are there any tests I can run from the router to determine we can't get addresses through DHCP.

Assigned static addresses work fine and users can connect to the corporate office.

Thanks.

Try specifying your DHCP server:

ip dhcp-server 10.100.2.100

I think you can run a 'debug dhcp detail' and it will show you proxy dhcp attempts, could be wrong. Might want to see if you can log/sniff at the dhcp server and look for proxied dhcp requests, though frankly, you might want to consider running dhcp on the router - it's fairly simple, and I've never had reliability issues with IOS dhcp.
