Mac OS X Server 10.6.8

DNS is running on a Windows Server 2003 box

Mac OS X Machine is NOT public facing.

 

I am having the strangest DNS problem. Everything was working just fine and then bam, gone. I don't get it.

 

 

 

Primary address     = 10.0.10.125

 

Current HostName    = newton.example.com

 

The DNS hostname is not available, please repair DNS and re-run this tool.

 

dirserv:success = "success"

What the heck is with the verisign-grs.com?? I've never seen that before. Shouldn't it be the host name?

    The command for going from host IP address to host name is dig -x.

     

    dig  -x 10.0.10.125

     

    Ignore the Verisign stuff; that's a response from the DNS root servers.

    If your OS X Server is using that Microsoft Windows Server DNS server here as appears to be the case based on that 10.0.10.24 address in the response, then the Windows Server DNS server isn't authoritative for the 10-net IP address, or it's misconfigured, or its malfunctioning.  Hand off the output from the dig commands to whomever is maintaining the Windows Server DNS configuration, and have them look at it.

    I'm going to blame my coworker, for sure. Thanks.
