NTDS Settings Properties has wrong DNS Alias

I have a DC that will not replicate from the PDC and found that the DNS Alias in the NTDS Settings Properties under AD Sites and Services is incorrect.  This box is greyed out so I can not change it.  I assume there is some way to refresh this value or remove and re-enter the correct one.  

This happened when the original PDC failed and had to be reloaded.

Thanks in advance for you help!

There are a couple candidates for the root cause of this one:  DNS island, Kerberos ticket, or improperly promoted DC.

To resolve a DNS island issue:  
Delete the old CNAME from DNS
Point all of your DNS servers to use a common DNS server as their preferred DNS server (I'd recommend the PDC); point the PDC at one of the other DNS servers
Run "ipconfig /registerdns"
Stop and restart the netlogon service.

Here's a very good article on how diagnose and to fix the other two:

Thanks for the response.  I read through the link you gave me and I am pretty sure I will have to demote the DC (which will fail) then use metadata cleanup to remove any reference of the PDC from it, remove it from the domain and then rejoin the domain and attempt another dcpromo.  Does this sound right?

I do have a question about using metadata cleanup - Am I supposed to run this on the DC AND the PDC or just one of them.  I assume the DC but I can't seem to wrap my mind around that.
