You have just added a Hyper-V host in the VMM 2008 Admin console. The host has all applicable updates installed. Yet, it still displays as “Needs Attention” in the Admin Console… how to fix?
Hmm… I have been researching this for awhile. Although you would not really know it, the host requires an upgrade to the Background Intelligent Transfer Service (BITS).
Updates for Hyper-V:

These updates will resolve the issue. KB956589 and KB956775 require separate reboots, trying to install a second update before restarting will generate the error that only 1 instance may run at a time…
Incidentally, I read about this solution on Mike’s Virtualization blog:

Once you have restarted the system after both updates, within the Admin Console Refresh the Host:
You should now be ok:
Problem solved!
