A bug in the DNS service in Windows Server 2008

I’ve seen quite an interesting behaviour of the DNS service in Windows Server 2008 for a long time without even thinking about the DNS service having a bug. Apparently there has been a fix for this issue out since summer time but it was not until Microsoft blogged about the bug a few days ago that it got my attention.

The problem is with secondary DNS zones that suddenly loses all (or many) records of the zone, which is not a very good thing I can tell you.

After reading through the description of the bug a couple of times I just sat there with my mouth open. This is exactly what I have been experiencing for some time now. So what is the moral of the story? Always check if it is bug!
