I trying to remove a DC so I can rebuild it.  The first time I ran DCpromo it failed stating it couldn't transfer the Operations Master.  I removed DNS from it and that solved that problem.  Now it states "That no other AD DC's can be contacted"  Do I want to proceed anyway?

I previously ran DCDiag /v and all tests passed except NCSecDesc.

The other DC is working fine and all the FSMO roles have been transferred.

How should I proceed?

If the other DCs can't be contacted, they may keep information in AD about the DC that's (now) missing.  You can clean that up, but it's not an ideal situation.

I would re-install DNS and give the DCPromo another try.  If you're still not successful, you can proceed as you are, kill the DC, and manually remove any traces from AD after that.

Added DNS back and it failed like before.  I'll proceed with the uninstall
