Recently our IT department upgraded our computers to windows 7 professional. Our domain controllers are running server 2003 r2. Once I add our new computers with windows 7 to our domain and restart, the DHCP service fails to start. When I try to restart the DHCP service I get the error that Access is Denied.
When I go into the registry I change the permissions for DHCP and TCPIP and add local service full control. Once I do this the DHCP service will run again but within a couple of hours or a retart the service quits and I receive the same error.
