I am really confused. Our Microsoft DNS on Windows 2003 has been working fine for years but now all of a sudden when I add this one IP address that falls in the range of 10.105.164.x it fails to create the reverse lookups for those IP addresses. I have a primary zone for 10.105.x.x configured and it works fine as shown below
Reverse Lookup Zones
The problem as I mentioned is that any IP address created for 10.105.163.x or 10.105.165.x or 10.105.166.x will create the corresponding reverse lookup but it will not work at all for anything I create in the 10.105.164.x range and does not even create the sub folder.
What is the problem here. Any help is greatly appreciated!
