_MSDCS DNS Zone

I have a domain with 2 domain controllers and 2 DNS servers. On each DNS server there is a zone called _msdcs.domain.local as well as a sub domain of msdcs.domain.local. Is this this the recommended configuration or should one of these be removed?

Any help is greatly appreciated

Assuming both DNS servers are AD integrated this is standard.

....It should be _msdcs.  Not sure what msdcs is.  Run DCDIAG /fix from the command line and it should take care of any misconfigured DNS settings.

Is this forest native to 2008 or have you done upgrades from Windows 2000?

Jorge had a really good explanation here  and I didn't want to take his work   http://www.winvistatips.com/whats-purpose-_msdcs-zone-active-directory-forest-root-zone-t691654.html

Jorge mentions the GUID you will also heare "DSA GUID" or "DC GUID" to refer to those records.   You might also see the _msdcs zone as a delegation under your domain (gray folder)

Thanks

It's actually not standard; you should have either a separate forward lookup zone called _msdcs.domain.local (with a corresponding delegation) or a folder named _msdcs inside the domain.local zone.  If you have both, you can get rid of one or the other.  If one contains a number of subfolders and records and the other one doesn't, get rid of the one that doesn't.

If you're saying you've got a zone named _msdcs.domain.local and one named msdcs.domain.local (without the underscore), get rid of the one without the underscore.
