I just installed DPM 2010 on a Windows 2012 machine. Everything appears fine but then I try attaching an agent and the server can never communicate with any agent.
I tried installing/uninstalling agents from the server and it times out. I tried manually installing the agent on the client machine and the server still can't communicate with it. I tried installing agents on machines with Windows 2003R2/2008R2/2012R2 and all have same results.
Here are the errors I'm getting on the server:
DCOM got error "2147942405" from the computer server.example.com when
attempting to activate the server:
{DA6AA17A-D61C-4E9C-8CEA-DB25DEA52A95}
I never had this issue in the past, but I always had DPM2010 installed on Windows 2008 R2. Could this be a DCOM security feature with Windows 2012?

I had the exact same error message with DPM 2016. The cause - I had removed
NT Authority\Authenticated Users
from the localUsers
group on the protected server.I added the
DOMAIN\DpmServerName
account as a member for the localUsers
group and the error went away.
