After yesterday’s Satchwell cloud server issue. I mimicked the problem again on my VM to see at what point after testing the issue was fixed. I have found the exact point FYI. it was a combination of:
Context: Main DC was taken offline permanently (unreachable) The domain in question is just the backup DC. Active directory was not reachable.
• Ntdsutil Seizing Roles
• DNS forward lookup zone to”domain.co.za”
• The registry edit: HLM\system\CurrentControlSet\Services\NTDS\Parameters\Src Root Domain SRV ( that must be changed to active Directory server you want to use)
• ADSI Edit: the Sysvol Subscription attribute: msDFSR-Enabled to false, restart the server, change the value back to true. restart and then active directory was working.
