(1) Check to make sure your SQL Server credentials are correct
(2) Make sure the agent is installed on the target server
(3) Update your BE server using liveupdate
(4) Update your agent(s) using the bulk update tool or manually
(5) SQL permissions for the account you'e using to connect need to have the appropriate permissions (backup operator should be adequate?)
I dont have sql server agent but i do have license? how can i download Agent for BE
The SQL "Agent" is just the serial that you install on the media server to unlock the cabability. You do need to install the Remote Agent on the remote SQL server machine, which is probably correct since you can backup the other database on the same server
any chance that rights within SQL are different for the two databases?
