After upgrading BE 2012 to BE15, I'm unable to Backup the Windows 2000 VMs using Backup Exec Agent for Windows (the last BE agent supporting W2000 is BE 2010).
When I try to do an Establish Trust in BE it fails:
Calling Method 'SetServerTrust'
BEMSDK Method 'MediaServerAdvertisementUpdate'
BEMSDK Failure Code: E0009B91
The job failed with the following error: An attempt to connect to remote computer has failed. The remote computer is running a previous version of either the Agent for Windows or the Agent for Linux. Due to security enhancements related to SHA-2 certificate migration, the existing trust between the Backup Exec server and the remote computer is lost. You must upgrade the remote agent and then reestablish the trust. Refer to the link below for more information: http://entsupport.symantec.com/umi/V-312-2.
