Weird...this shows up with BE 2010 and the recommendation was a move to BE 2010 R2.

So this should have been dealt with in BE 2012. Have you installed SP2 and then push-installed the updates out to the remote servers?

Make the following changes create/modify the below key on the Media Server

Key : HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\VirtFile
Value: VFF Extended Timeout
I set the value to 240.

If the extended timeout edit doesnt work initially you can increase the value of the time out to 480 and try again and then 600 See tech note below for documentation
