Hi,

I have installed DPM on a windows server 2008 R2 enterprise.

We created the backup routine very well, but we have other 3 servers to 
manage.

I installed successfully the agent on one of this 3 servers.

I am getting error when I try to install on the other 2 computers, I 
installed the MOM Agent manually, but the error still occurring.

===========

Protection agent version: 3.0.7558.0
Error: Data Protection Manager Error ID: 270
 The agent operation failed on spawks001.spa.local 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 computer.domain.local is a workgroup server, the password for the DPM 
user account could have been changed or may have expired.
Recommended action: Check the following to troubleshoot this issue: 
1) If the agent is not installed on computer.domain.local, 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 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 spawks001.spa.local 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.
 If the computer is protected by another DPM server, or if the protection 
agent has been uninstalled, you can remove the record of the computer from 
this DPM server.
 Remove the record of the computer from this DPM server.

the DPM Deployment Guide. or
2) In DPM Administrator Console, uninstall the DPM protection agent. In the 
Management task area, on the Agents tab, select the protection agent, and 
then in the Actions pane click Uninstall.
 If the computer is protected by another DPM server, or if the protection 
agent has been uninstalled, you can remove the record of the computer from 
this DPM server.
