Cannot start workstation service on DC

Question

I followed this KB to disable SMBv1 server and client with Group Policy. After that, my DC seems down as I got many error that no AC server is founded in my domain. I then found the workstation service cannot be started, it said "Windows could not start the Worksation service on Local Computer. Error 2: The system cannot find the file specified".

The registry I changed are here:

https://msegceporticoprodassets.blob.core.windows.net/asset-blobs/4023804_en_2

However, even I deleted these new created registry keys, I still cannot get my DC back. This is the only DC in my environment. Help!!

Solution 1

I resolved it myself. Not sure why, but i ran the command

sc.exe config lanmanworkstation depend=bowser/mrxsmb10/mrxsmb20/nsi

and

sc.exe config mrxsmb10 start=disabled

Reboot the server; then run

sc.exe config lanmanworkstation depend=bowser/mrxsmb20/nsi

After reboot the server again, now I can start the workstation service and other services now. my DC is back!

I have same issue in windows server 2012 and 2016. I resolved it myself. i ran the command

sc.exe config lanmanworkstation depend=bowser/mrxsmb10/mrxsmb20/nsi

and

sc.exe config mrxsmb10 start=disabled

Reboot the server; then run

sc.exe config lanmanworkstation depend=bowser/mrxsmb20/nsi

After reboot the server again, now I can start the workstation service and other services now. my DC is back!

So, you broke your only domain controller... I would advise finding a consultant and being prepared to pay to untangle this mess. While you're at it, it would probably be worthwhile to see about getting a secondary DC setup and doing backups.
