vastool command to find out domain controller's Windows Operating system version (4281148)

Is there a vastool command to find out the operating system on the domain controllers (DC)?

Is there a command to find out windows operating system version in QAS?

For a  domain controller's operating system the following command can be run on a client that is joined to the domain:

for s in `/opt/quest/bin/vastool info servers | sed '1d' | cut -d. -f1`; do echo $s; vastool -u host/ search -q "(&(cn=$s)(objectClass=computer))" operatingSystem; echo; done

Another useful command is to one to find the Active Directory PDC:

for s in `/opt/quest/bin/vastool info servers -s \* | sed '1d'`; do echo $s; /opt/quest/bin/vastool info cldap $s | grep PDC; echo; done
