This is a recently discovered issue that has already been posted by Michael Michael on his great blog site, and there is an upcoming KB article as well. I’ve assembled step by step instructions for the SQL-challenged such as myself. The SQL tools required are free to download and explained at the bottom of this post. Enjoy!

Windows 2000 Server and Advanced Server virtual machines display an Operating System property of 'Unknown.' If the Operating System property is set manually, it will revert to 'Unknown' following an automatic SCVMM refresh. There are no errors associated with this change.

Resolution

Follow Michael’s post here, or the step by step instructions below. Same content, more pictures here. ;)

Instructions

1. Close the SCVMM Admin Console

2. Open the MICROSOFT$VMM$ database
