Hi
We have a few problems with one of our servers, it is a Windows Server 2003 R2 server, a single domian and the only server on site. I havent been looking into this myself today but just got landed with it about an hour ago and am scratching my head.
No users can login and it seems like DHCP has lost the link to AD. DHCP has the red down arrow on and asks to be authorised but the option is Unauthorise, when I click that it does nothing and then when I click Authorise again it does nothing, still the red down arrow.
So far I am told DNS and DHCP have been reinstalled and the server rebooted. Can get into AD ok and no errors appear. Ill paste the errors we are getting below.
DCDIAG report:
Also getting following errors in event log
