My company ran into a problem with the BE Appliance 3600 recently with Windows updates through OpsCenter. The main account to OpsCenter is only a local admin account, which is fine, but the only way to update any of our servers on our network is to be logged into a domain account. I am sure that every company has different means of updating their Windows driven servers, but having a domain authenticated OpsCenter account would definitely help us out. 

I was able to download Windows updates manually by signing into the appliance with a domain account. Yes, this manual method works, but it is very cumbersome.
