I do not have much experience with backup/restore to windows server images. I have a Windows server 2012r2 with sql and an accounting program. It is/was joined to a domain. I had to do a restore from backup image (I use Novastor backup server). The server had spinning disks and I replaced them with solid state discs, then did the restore on them. The server now does not allow me to login with my active directory credentials, just the local Admin. I don’t think it is linked to the domain properly anymore. Any advice on what I need to do to get this back to normal?
I really was hoping the restore from Image backup would work without issue, but maybe it did not because of the new hardware installed? I do not want to do a fresh install and have to reinstall & reconfigure everything. Thoughts?

Thanks.

    why cant you use the local credentials? at least that would get you back into the box for further troubleshooting. This must not be a DC, right? Login locally, then rejoin the domain. – Larryc Mar 01 '20 at 03:50

    Did you try to restore to the same server? Maybe it is a driver issue and your server could not connect to your AD? – Stuka Mar 01 '20 at 12:57

    This is not really superuser.com - this is a place from the site rules for professionals following proper business practices. Starting with "I do not really know what I am doing" sort of makes me vote to close. – TomTom Mar 02 '20 at 15:59

I assume, it happens bacause of "computer credentials" change. Computer account password refresh is automatic process that happens between computer and domain controller without notification to or interaction with the user. Check 2-nd reason here

Just login with local Admin and rejoin domain.

    Thanks batistuta09. I will look at just rejoining the domain as you have pointed out. – alv Mar 03 '20 at 18:31

    I was thinking that I could also do a P2V on this to make life much easier as well. – alv Mar 03 '20 at 18:32

    For P2V, I'd advise to check this article regarding convertors - https://www.hyper-v.io/migrating-cloud-easy-experience-choosing-p2v-converters/ – batistuta09 Mar 04 '20 at 11:20
