Active Directory screwed
Hi
My primary DC failed and can not get it running and secondary fails to start Active Directory. This is the dcdiag output.
Any help would be highly appreciated.

Time Provider NtpClient: This machine is configured to use the domain hierarchy to determine its time source, but it is the AD PDC emulator for the domain at the root of the forest, so there is no machine above it in the domain hierarchy to use as a time source. It is recommended that you either configure a reliable time service in the root domain, or manually configure the AD PDC to synchronize with an external time source. Otherwise, this machine will function as the authoritative time source in the domain hierarchy. If an external time source is not configured or used for this computer, you may choose to disable the NtpClient.

hi
What OS are the DC's?
Windows 2016
Are they both GC servers? - If they are you can try seizing roles on the second AD server then rebuild the failed primary.
Not sure.
Do they each have DNS servers pointing to themselves, not each other?
primary server is completely gone. It has been deleted by mistake
Does DHCP have both DNS servers in the scope options?
Yes
Also, reboot a client to see if it can connect to the 2nd server as DNS.
nslookup everything seems to work fine of that DNS

C:\Users\Administrator>nslookup ads01

To see if a server is a GC server you can check this in Active Directory Sites and services > NTDS > Properties, you will see a box that should be checked for GC (Global Catalog)

OK, how many users/devices are there?
Are they physical or virtual DC's?
Did you take a recent full backup of the DC including systems state (inc. SYSVOL) and AD database?

This solution is only available to members.
To access this solution, you must be a member of Experts Exchange.
I would also say you'll need to restore hence my question regarding backups.
Did you delete the computer object in AD?

MAS has greatly helped me on private chat.
We had to restore the old ads and recreate the new one as a backup.
