DPM Client on Server 2008R2x64 - runs consistently; never has failed.
DPM Client on SBS 2011. Has failed every couple of weeks or so since I installed it 6 months ago.
Every time it fails, it shuts down. When I restart the service, it starts and stays started for 8 minutes, then stops again. This continues until I reboot the client server. When I reboot the client server, the DPMRA client connects and makes backups for a week or two then does the same thing again. This behavior has been consistent no matter what updates or hotfixes/rollup are installed on the DPM server or client. Rebooting my exchange server every week or so is not very convenient.
Keep in mind that the other two client continue using the DPM server during this with no problems.
Also, the SBS machine has no other failures or service interruptions in VPN, Exchange, or AD.
