Ok we currently just went through a network revamp. I deceided to reinstall everything instead of trying ot migrate stuff to my new servers. Everything has gone perfect with the exception of my DHCP Server. I installed a toally new domain joined all my pcs to that domain using static address's. Now it was time to install the new DHCP Server so turned off the old DHCP Service and started up the DHCP service on the new server. Everything seems to be running fine. No errors in the event log, but none of my pcs can obtain a DHCP address? Anyone know why? My Domain server has the following services running on it - AD, Print, DNS, DHCP.
