I have five DC's, one at each site. For some reason, on my DCs, the DNS entry for one of the other servers is missing. I am unable to ping that server via hostname. I can reach it by IP and everything else seems to be fine. When I look at WINS, the entry is there. When I look at DNS, the entry is missing. I try to manually add it and I get the following error.
"Warning: The associated Pointer (PTR) record cannot be created, probably because the references reverse lookup zone cannot be found."
When I right click on the forward lookup zone and go to the name servers tab, the server I am unable to ping does not show the IP address, it says unknown. I tried to correct this yesterday but this morning it was back to unknown again.
I did a nslookup and this happened.
C:\Users\administrator>nslookup
DNS request timed out.
timeout was 2 seconds.
Default Server: UnKnown
Address: ::1
C:\Users\administrator>nsl

I found the following in the event log two weeks ago. No other events have been logged since this log.
Log Name: DNS Server
Source: Microsoft-Windows-DNS-Server-Service
Date: 1/24/2014 4:49:02 PM
Event ID: 4015
Task Category: None
Level: Error
Keywords: Classic
User: N/A
Computer: server
Description:
The DNS server has encountered a critical error from the Active Directory. Check that the Active Directory is functioning properly. The extended error debug information (which may be empty) is "". The event data contains the error.
After deleting the old records, I could add new ones and it works for a few minutes but then everything stops working again and the entries are back to the way they were initially.
How do I correct this DNS entry?
Thanks,
Justin
