Hello,
I have a problem that I’ve been racking my brains out with the last few weeks that I would love some help with, if anyone wants a challenge…
To begin with here is my topology.
We have two sites (MAIN and CC) connected via a 10MB pipe using MPLS and each site has their own separate internet (same ISP) on each end, the domain is called xyz.com.
Each site has two Windows 2008 R2 domain controllers and running active directory integrated DNS. The MAIN site doesn’t show any issues with the best practice analyzer, the second location CC, has errors with the BPA mainly, “DNS: Zone _msdcs.xxx.com is an Active Directory integrated DNS Zone and must be available. Root hint server 128.9.0.107 and 198.32.64.12 must respond to NS queries for the root zone. Same ISP, sites are in the same state (maybe 20 miles apart).
I have tried everything I can think of to resolve this error, including running dcpromo and completely removing AD/DNS from the CC location (both servers), renaming the DNS directories in the system32 directory on both servers waiting a day for replication, running dcpromo again letting it sync up with the MAIN
location only to have this error stick around.
Under the xyz.com properties tab in DNS all the DCs show up under the Name Server tab. Reverse Lookup Zones have all of the subnets listed and they appear to be working, I thought about doing delegation but there isn’t any subdomain, everything is listed under xyz.com. The clients in the CC location don’t appear to have a problem but Windows is saying this is a critical error so I don’t want to ignore it. I’ve tried making both severs in the CC locations bridge head servers and all servers are global catalogs to see if that does anything—which it doesn’t, so I’m completely out of ideas.
Any suggestions I’m overlooking? HELP!!
