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.

Hi,

What OS are the DC's?
Are they both GC servers? - If they are you can try seizing roles on the second AD server then rebuild the failed primary.
Do they each have DNS servers pointing to themselves, not each other?
Does DHCP have both DNS servers in the scope options?
Also, reboot a client to see if it can connect to the 2nd server as DNS.

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
Server:  ADS01.kaufmann.local
Address:  192.168.1.15

Name:    ads01.kaufmann.local
Address:  192.168.1.15


C:\Users\Administrator>nslookup app01
Server:  ADS01.xx.local
Address:  192.168.1.15

Name:    app01.xx.local
Address:  192.168.1.16

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)

Do/did you just have the 2 DC's?

Problems using Powershell and Active Directory?

Managing Active Directory does not always have to be complicated.  If you are spending more time trying instead of doing, then it's time to look at something else. For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why

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?

HI,
Your easiest option is to find backup of your FSMO holder as your additional domain controller is not healthy to work on its own.  Instead of wasting your time fixing please try to restore the backup.

Thanks

I would also say you'll need to restore hence my question regarding backups.
Did you delete the computer object in AD?

A couple of articles on restoring DC's:

MAS has greatly helped me on private chat.

We had to restore the old ads and recreate the new one as a backup.
