Question : The disk is offline because of policy set by an administrator

Just spun up Hyper-V and five VMs running Wndows Server 2008 R2.  Rock solid so far, everythng just works -except- when I plug in my 1TB IOMEGA eSATA drive the O/S sees it but it remains offline.  I get:
"The disk is offline because of policy set by an administrator".  I have read and read but nowhere can I find how to allow this in group policy or wherever.  Please advise.  Thanks!

Answer : The disk is offline because of policy set by an administrator

On VMs that are both workgroup and domain I was able to right click on the offline and set the disk to online then right click again and initialize.  That solved my problem.
