Unable to recover a windows server using sdr custom disk

Hi all ,

I am using Backup Exec 2012 . I taken backup of few servers with SDR enabled .

I created one Custom sdr disk . Using this disk i tried to recover one of our windows servers .

But at final step (Recover ) , it is giving the following error .

"Backup Exec server cannot authorize the backup exec for the remote agent running on this computer".

If any idea on this . Kindly share your Valuable information in-order to reslive the issu.
