I'm having some very weird issues with migrating my 2012 Domain Controller to a new 2016 server. Most articles I have read state that all I need to do a set up the 2016 server as a Domain Controller and move the FSMO roles... then when all looks good, I can remove the Domain Controller on 2012. Well this certainly was not the case for me. DCDiag on the 2016 server is showing this:
Starting test: Advertising Warning: DsGetDcName returned information for \\ds1.dir reach DS2. SERVER IS NOT RESPONDING or IS NOT CONSIDERED SUITABLE. ......................... DS2 failed test Advertising Starting test: NetLogons Unable to connect to the NETLOGON share! (\\DS2\netlog [DS2] An net use or LsaPolicy operation failed with er ......................... DS2 failed test NetLogons
I found the following article that seems like it would help my case: https://blogs.technet.microsoft.com/ziggy/2013/08/20/sysvol-on-newly-promoted-dc-is-not-synchronising-but-replication-looks-ok/
I am currently trying to add the Administrators group to the "Default Domain Policy", which is explained in this article: https://support.microsoft.com/en-us/help/2567421/dfsr-sysvol-fails-to-migrate-or-replicate,-sysvol-not-shared,-event-ids-8028-or-6016
When I add the group, GPMC returns this error: "the system cannot find the path specified"
I'm really not sure what to do from here. I had to remove DNS from the 2012 server because it was giving issues with my new 2016 DC. I cannot demote the 2012 DC because it is telling me it cannot contact the other DC. I'm afraid to touch anything in fear of losing my whole directory.
Thanks for any help you can provide!
