Migrating win 2003 server that was hosting dhcp to Windows 2008 r2 server. Dchp authorized and activated.
Stopped dhcp server on win 2003 and my test client not able to find dhcp server. No dhcp relay agents activated on any other server. Very small shop with only 3 servers, firewall and router. No bootp or dhcp settings activated for dhcp. Not sure were to look next.
