DPM: Agent unreachable - Agent communication error
DPM agents on some of the protected servers are not reachable because of communication error.
DPM Server: {0}
Resolution steps:
If you recently installed a protection agent on the protected server, the computer may be restarting. Wait a few minutes after restarting the computer for the protection agent to become available. If the problem persists, do the following:
1) Verify that the target server is accessible remotely from the DPM server.
2) If a firewall is enabled on protected server, verify that it is not blocking requests from the DPM server.
3) If protected server is a workgroup server the password for the DPM user accounts may have changed or expired. To resolve this error, run SetDpmServer with the -UpdatePassword flag on the protected computer and Update-NonDomainServerInfo.ps1 on the DPM server.
4) Restart the DPM Protection Agent service on protected server. If the service fails to start, uninstall the protection agent using Add or Remove Programs in Control Panel on the protected server. Then in the Management task area of DPM administrator console, on the Agents tab, in the Actions pane, click Install to reinstall the protection agent on that server
