Hi,
Previously i was using DPM 2010 and DPM agents were installed on my mailbox servers for taking backups.
Due to my DPM server crash, i have build DPM 2012 server and i have removed my previous DPM agent from my exchange mailboxes manually.
Now when i trying to install new DPM server agent on mail servers following error appears.
'Protection Agent version 4.1.3313.0
Error: Data Protection manager Error ID: 270
The agent operation failed on SERVER NAME because DPM could not communicate with the DPM protection agent. The computer may be protected by another DPM server, or the protection agent may have been uninstalled on the protected computer.
If SERVER NAME is a workgroup server, the password for the DPM user account could have been changed or may have expired.
Check the following to troubleshoot this issue:
1) If the agent is not installed on SERVER NAME, run DpmAgentInstaller.exe with this DPM computer as a parameter. For details, see the DPM Deployment Guide.
2) To attach the computer correctly to this DPM server, run the SetDpmServer tool with the -Add option on the protected computer.
3) If the computer is protected by another DPM server, or if the protection agent has been uninstalled, remove the protected data sources on this computer from active protection. Then, remove the entry of this computer from the Agents tab in the Management
task area.
4) If SERVER NAME is a workgroup server, run SetDpmServer with the -UpdatePassword flag on the protected computer and Update-NonDomainServerInfo.ps1 on the DPM server to update the password.
5) If the DPM server and the protected computer are not in the same domain, ensure that there is a two-way trust setup between the two domains.
I am using domain administrative credential to install agents.
Kindly help me to solve this problem.
