I've started to notice this too. I run an OS Discovery Scan weekly and then follow up with Compliance scans against the dynamic assets for each OS. For example, I scan Windows 7 assets with the SCAP Benchmark for Windows 7. Now I'm seeing a bunch of these systems in the 2008 dynamic asset list.
I am running credentialed OS scans and it still thinks these systems are 2008/Vista instead of just Windows 7.
Did you ever get a fix? I update my plugins weekly, but haven't noticed any changes.
I know that there is a close correlation to these two Operating Systems, but is there a way to prevent Desktops from being listed in with the Windows 2008 Servers? I have tried all the recommended OS Identifications plugins (with and without credentials), but they still show up.
Would there be a way to modify the Windows 2008 Assets to exclude the Desktops with a REGEX? Maybe based upon host-name?
