After a little smoke testing I decided to take the dive and upgrade my work notebook to windows 8 Pro.  Everything went great until I added it to the domain.  Once I added it to the domain I was getting this error:

The problem stems from that we use a Windows Server update services to filter updates, this ensures that updates do not go out to the corporate computers without testing and approval.  If you look at the bottom of the screenshot posted above you will notice the following:

You receive updates:  Managed by your system administrator

The problem I experienced is that the WSUS server is on an older version and returns and error when my windows 8 machines attempts to connect to it for updates.  To bypass this for now you can do one of two things.

Option 1:

• Click the hyperlink “Check online for updates from Microsoft Updates”

Option 2:

• Open regedit at HKLM\Software\Policies\Microsoft\ Windows\WindowsUpdate
• Remote the keys for the WUServer
• Check if the domain admins to see if these keys are set by profile on reboot.  If they are, they may add an exception for you.

After that, you should be able to update Windows 8.
