I have windows datacenter on my root partition, that installed windows update.
I have enterprize on my children, they will not update. For them to update should they be datacenter too, or can you not install windows updates on virtual machines?
root partition is not activiated.
Also, have no roles or features installed on my children.
Found a solution, gathering the updates manually from http://catalog.update.microsoft.com/v7/site/home.aspx
But would still like to sort the reason why the it didn't check for updates properly
The problem is outdated driver on the virtual machine bus virtual adopter, when you in stall windows server 20008 service pack 1 the driver gets updated and you can use windows update to download and install your updates automatically. You can find sp1 on the catalog link above.
Thanks for the help
