You should try a 'dig microsoft.com +trace' and see where the problem resides.

Since we couldn't pinpoint the cause, the problem went on for about 5 hours and then magically fixed itself... we were all left scratching our heads. Yesterday, (two weeks after the initial problem and curiously at around the same time) the problem reappeared for about 30 minutes. All of our servers (affected and non-affected) are running BIND 9.5.1-P1. The failed queries return timeouts or SERVFAILs. Restarting BIND did not fix the problem. Nothing suspicious in the logs. Has anyone else experienced this sort of thing recently? Can anyone point me in the right direction?? Is this even a BIND issue??? I'll be more than happy to provide any further details!
