    Hi,

    In our environment we are using DPM 2010 and we are protecting file and application server.we are having remote database server we created protection group for application server and scheduled short term backup in disk and long term backup in tape and backup happened according to the schedule and everything was fine.

    we have changed the password for DPM admin account since then the protection agent is unable to communicate with the DPM server and backup job failed. DPM error code 270 is logged in agent status.

    Is there any other way to make the protection agent to communicate with the DPM server again without uninstalling protection agent.so that our protection group should take backup according to the schedule,

    thanks & regards,

    Siva 

    Thanks Siva Aadhi-CIT. MCITP

    Hi Siva,

    The credentials suppplied are only used at the time of the Agent deployment.  Changing your password after agents are deployed does not effect anything in DPM.

    If the error while communicating with the protection agent is ID 270, then help us with the details as well. Also check the event viewer of the File server which is being backed up - Application and System logs for any errors.

    Also check the following - Does the DPMRA service on the File server start when we refresh the agent status from the DPM console.

    Most common reasons for getting ID 270 is due to Firewall. Would recommend you to check that front too.
