    I setup a domain controller using an eval version of Server 2012. I rolled this server out to a production environment while I waited for my server licenses to arrive.
    I soon realized that you cannot activate an eval license if you have already run DCPROMO. After demoting/promoting my server I was getting this error (among many others).
    I cannot express how happy I am that I found your blog. I was preparing to….??

    Thank you very much for this fix! I had promoted/demoted a couple of times due to the error message, thinking I had missed a step. After double/triple checking my steps nothing was missed, and the error message still existed. Came across your fix, and BAM! Up and running.

    Thanks a lot for the RegKey change.
    In our situation, we have 2012 R2 domain controller, with all FSMO roles.
    Created a replica with Veeam and put the replica in an isolated lab environment for testing.
    Nothing was working for AD DS, with the RegKey change from 0 to 1….BOOM!!!
    Great info!

    Spent many hours to migrate from a 2003 server to 2012R2, and after forcing unregistering the old server from the domain [dcpromo], domain was gone!!! I was desperate, imagine customer’s employees coming back from summer holiday next Sunday to a non functional environment? you just save me from big embarrassment!!!

    I have tried to dcpromo and keep getting error domain controller could not be contacted for the domain. I have tried the method that you suggested but no luck for me. The registry for the sysvol key from the primary DC is 1, anyway as you suggested if the value is 1 then change to 0. After that change it back to 1 from 0 and exit. I tried to dcpromo again and getting the same error. Any further advise? Thanks.

    What a dude…. I’ve been wracking my brains for hours with this and was thinking it to be with replication, even though we don’t have replication setup. I have a test environment where I took a system image of a domain controller but after a few weeks I ran into the problem. Seems to be working now, didn’t even have to restart.
