The inherited permissions of the server in ADUC were removed so the DC no longer recognises itself as a DC.
dcdiag /q
[Server01] LDAP search failed with error 58,
The specified server cannot perform the requested operation..
***Error: The machine, Server01 could not be contacted, because of a bad net
response. Check to make sure that this machine is a Domain Controller.
Can I reset the permissions using regedit as I can not see the ADUC any more?
Thanks
