We have 11 clinics serviced by one data center but only 5 of them get their DHCP from us. The others have local servers. We are putting into place a DHCP server to replace the current one that is having hardware issues. I have created all the scopes and I have authorized it and unauthorized the old one. However. when I am trying to release - renew on a test machine it does not find the new DHCP server. I have even put in the Gateway router a line (ip dhcp-server x.x.x.x) to point to the new dhcp server.
Am I missing something else? Yes I have activated the scopes and I can ping the new server, in fact I remote into the new server. I have checked any other routers and firewalls to see if they point dchp somewhere else and they do not.
Does this normally take awhile to get replicated and I need patience?
