Hi,
I recently demoted a troublesome 2003 SP1 DC from AD. There was left a 2008 R2 DC in the same site, however, when i go to ADSS and into that one specific site from any DC now, i get the error "Data from Servers is not avaialbe from Domain Controller <servername> because: An operations error occured. Try again later, or choose another DC by selecting Connect to Domain Controller on the Domain context menu."
DCdiag shows no apparent problems and all tests pass.
So could i simply delete the corrupted site and recreate it? All the other sites are ok.
