Lost Connection during Child Domain Installation

Bringing up a new 2012 R2 server at one of our off site facilities.  During the AD installation we lost all communication to the parent domain.  Unfortunately the server was rebooted during the night.  This morning started the AD installation again and it stalled at the replicating schema screen which is where it was when the communication dropped yesterday.  At my parent domain I don't see any entries for the new child domain.  

Need some direction on where to start to unwind this issue.

You will need to check and see if it actually was replicated to your domain.

Use Ntdsutil to check and see if there are any references for this child domain controller.

You can also use netdom query dc

From the Child perform a force removal of the DC and see if that removes the entries from the Active Directory domain. Use the below link which outlines these steps.

If the force removeal does not work then do a metadata cleanup using the NTDSUtil command.

Aside from that once you have removed the child DC you can then re-promote it back into the domain as a child domain.
