Error details: Unknown property Recommended action: Review the error details, take the appropriate action, and then retry the agent operation.
The manual adding of the server to the DPM server via the DPM Shell worked well, however, it obviously has issues communicating with the 2k3mail server. You need to install agent on two domain controllers since replication happens in regular intervals. On replications, domain groups get recreated. That creates problems. Please follow below steps install agents on parallel DCs. The protection agent installations cannot occur simultaneously on the domain controllers that are in parallel replication mode.
Wait for the replication to occur between the domain controllers before you install the protection agent on the second domain controller. The repadmin is a utility that you install with the Windows Server support tools. Note Two or more Please let me know if you face any problems further.
I respect your knowledge, however, I am unclear how the above is going to resolve the issue. Looking for your response. You are right. You have already successfully installed agent on 2k3data server. After that install agent on second DC by steps: 5, 6 and 7 steps. Thanks, krisnaru. It looks like AD replication caused agent install to fail.
Lets do the below steps and let me know the result. DPM Agent Coordinator failure - error Reply to author. This is a problem where the Windows installer gets out of whack. I used the Windows Install Clean-up utility msicuu2. The strange thing is that this server is also protected by a secondary DPM server. The secondary DPM server says that the agent is not reachable. I will probably try uninstalling and reinstalling again. This occurs even you clear the automatically restart option.
To do this, at the command prompt, type the following command to query the related registry entries:. Both the DPM server and the computer to be protected must be connected to the network during installation of a protection agent. Is a firewall enabled on the computer to be protected that could be blocking requests from the DPM server? If a firewall is enabled, you must configure the firewall to allow communication between the DPM server and the computer to be protected.
For information about how to configure the firewall, see Set up firewall exceptions. If a firewall is enabled, you must configure the firewall to allow installation of a protection agent on the computer. The Remote Registry service must be running on both the DPM server and the computer before you can install a protection agent. In Administrative Tools, start the Remote Registry service and then install the protection agent.
RPC must be available.
