exchange 2010 exchange management console, access denied. Time sync issue?

I installed Exchange 2010 on Windows Server 2008r2, my domain already has an Exchange 2007 organization present.

During the Exchange 2010 installation, two errors occurred:

1. Upon the hub transport role install, it failed with msexchangeadtopology service could not be started. This was fixed by adding the Exchange Domain Servers group to the server object in AD.
2. Upon the mailbox server role, msexchangesa service could not be started. This was fixed by adding the Exchange Enterprise Server group to the server object in AD.

After these errors where corrected, Exchange installed fine. No problems

The first time I opened the management console, and tried to open the local Exchange site, I received an error that the console could not communicate with win2k8ex.domain.local. After researching I saw there was a time sync issue, so I ran net time \\dc /SET YES, restarted and the console worked fine.

Now, the console gives me an error every 15 minutes telling me access is denied for the current user with authentication as kerboros, if I run net time and restart it works fine but then eventually throws the error.

I did some research on the Microsoft TechNets but didn't find anything that really helped me. Please keep in mind the servers time match down to the minute whenever this error occurs, but for some reason net time and a restart resolves the issue, but only temporarily.

The article I read about net time had a settings change in VMWare, but I am not running WMWare, there is nothing virtual about my environment
