DPM 2010 agent installation on Domain Controller

Question

Hello all, recently I tried to install the agent from my DPM 2010 server onto a Win2K8 Domain controller which failed (used a Domain Admin's credientials for the install, and on trusted domain). I remember in DPM 2007 you needed to install the agent through
command line. Can someone post up the correct steps to get a DPM 2010 agent installed to a DC?

Answer 1

Same issue here.
Pushing a DPM 2010 agent to a Windows 2008 DC fails with the error:
============
You cannot install the protection agent on SV-MGMT-03.xxxxxx.nl because access to the computer has been denied.
============
The DPM 2010 agent software is installed but DPM doesn't add the server. With an attach i can add the server but DPM 2010 cannot communicate with it.
===============
Protection agent version: 3.0.7696.0
Error: Data Protection Manager Error ID: 270
 The agent operation failed on sv-mgmt-03.xxxxx.nl 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 sv-mgmt-03.xxxxxxx.nl 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 sv-mgmt-03.xxxxxxxxx.nl, 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 sv-mgmt-03.xxxxxxxxx.nl 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.
==============
Anyone a solution for this?
