Trust Anchors zone in Windows 2003 DNS

Question

OK, I could be wrong...but I don't ever remember seeing this on my DC's before. Simple 2003 domain with 8 DC's around the U.S.

I had to get into DNS to add a host record and saw this forward lookup zone.

Has it always been there and I've been blind? How does it get there? Am I drunk?

Answer 1

I found out myself:

What's funny is that my server is a W2k3 server...so not sure why it is even showing a trust anchor...but oh well.
