while authorize dhcp server getting error
" the DHCP service could not contact active directory."

we have another backup dhcp server, even there also getting same error.

so we tried to unjoin the domain and rejoin in dhcp server, but while rejoining the domain also we are getting one more error  
" Changing the Primary Domain DNS name of this computer to "" failed. The name will
remain "<DNS domain>.<top level domain>".
The error was: No mapping between account name and security IDs was done"

even then with the same error after joining the ad if we we try to login the the machine with AD user name its giving error  
" the security database on the server does not have a computer account for this workstation relation trust"

please help resolving the issue. formatting the dhcp server and reinstall will solve?
