Exchange 2010 - DNS Registration issues?

Hey Guys,

Exchange 2010 machine in which I have been plagued with the same issue since we stood up the box. MX services seem to be running, but  every 15 mins or so I get the follow events that pop in the application log.  < see attached picture >

I am thinking all of the DNS settings required for AD are not established, therefore I am popping these events. That said, I am not sure as to how to refresh all of those DNS entires and settings to make Exchange happy. :)

Your assistance is appreciated!

I looked up Error code=8007077f and there is a forum that references the exchange servers's machine accounts supposedly need to reside in the COMPUTER OU.

I do have the machine accounts located in a different OU called "domain servers".  Anyone with Exchange 2010, can you confirm your exchange machine accounts default location and if you moved it out of that OU, did you experience this issue?
