I had a similar issue with a DPM agent on a 2k8R2 DC. You can remove the agent from within the server through Programs/Features in the control panel. Then remove the agent from within the DPM Console and disable the firewall on the SQL Server, and finally do regular install of the agent from within the DPM console. That's the process that worked for me.
