Problem:  After making some changes to a server the 2010 Data Protection Manager agent was no longer communicating with the DPM Server.

Solution:  Re-installing the agent did not completely fix things.  The following command directed the agent to communicate to the DPM Server:

C:\Program Files\Microsoft Data Protection Manager\DPM\bin\ setDPMServer -DPMservername DPMSERVER

Configuring dpm server settings and firewall settings for dpm server =[DPMSERVER]
Configuring dpm server settings and firewall settings for dpm server =[company.com\DPMSERVER]
Configuration completed successfully!!!

This is the manual process for installing the DPM 2010 agent.

Another tip:  If the DPM agent will not communicate after a manual install, try the same procedure after disabling the firewall (temporarily).

I encourage trying this even if the Windows firewall statements look correct. In one troublesome instance the DPM client was only able to communicate after I disabled the Windows firewall and ran the setDPMServer -DPMservername DPMSERVER command.  The DPM agent lost its connection after I enabled the firewall again but at least this set me in the right direction!

Feel free to post comments or questions regarding DPM.  I'm happy to help!
