Can not authorize DHCP server

view full story

http://serverfault.com – I have run into a strange DHCP problem. The thing is the service is running, but the DHCP is not authorized. However, when I try to do it by right clicking, the option to authorize is not there - I can only choose to unathorize it. (Sorry, can't includa a SS). When I click unauthorize, I get the error "The parameter is incorrect." So now I'm stuck with unauthorized DHCP server that for some reason only can be authorized. I have tried all the usual stuff except re-installing the service. Anyone here have a clue what it can be? (HowTos)
