I had a backup domain controller have issues which caused me to demote it, unjoin it from the domain, and then join again as a member server. Since then it seems, the timer server service has not worked. Last night I promoted the backup to domain controller again (I only have 2 servers so needed to be done) but the problem persists.
I have tried everything I can find to try - I have checked and double-checked all the registry entries defined by Microsoft to set up for a time server and I have stopped, config'd, restarted the time service at command prompt every which way I can find to do so - i.e. http://ben.goodacre.name/tech/Domain_Controller_is_not_advertising_as_a_time_server_Error_in_dcdiag_(Windows)
. Also DCDiag reports at the beginning that it is not advertising as a time server. All the FSMO roles are correct and there are no other DCDiag issues.
What else can I do?!
