One common problem that Exchange administrators experience with Microsoft DPM 2007 Manager involves agent deployment failures. There are several factors that can cause a DPM 2007 agent install to fail, most of which are fairly simple to resolve. The first thing I recommend doing to avoid a failure is: Check your server clocks. The agent deployment process will not work unless the clock on the DPM 2007 server is set to the same time as the clock on the computer onto which you're deploying the agent. DPM agent deployment failure can also crop up when the DPM 2007 server cannot communicate with the server that you're trying to deploy the agent on. Usually, if the two servers can ping one another, the deployment will work. A DPM 2007 server needs to be able to communicate through several different firewall ports. If you are using Windows Firewall, these ports are automatically opened as a part of the configuration process. The table below shows a list of ports the DPM 2007 uses.
Table 1. Windows Firewall ports and their uses. Sometimes the cause of agent deployment failure is simpler. I recently had to troubleshoot an agent deployment failure for a client. I was getting frustrated because everything appeared to be configured correctly. In the end, the problem happened because the DNS host record for the DPM server was incorrect. The host record contained an incorrect IP address, so the server that the agent was being installed on could not communicate with the DPM server. If all else fails, open the Service Control Manager and look through the list of services running on the server. Also, be sure that all of the services that are set to start automatically are running. Creating a DPM 2007 protection group The next step in the DPM configuration process is creating a protection group. Begin by selecting Data Protection Manager's Protection tab. Then click the Create Protection Group link found in the Actions pane. Windows will launch the Create New Protection Group Wizard.
Click Next to bypass the wizard's Welcome screen and you'll be taken to a screen showing a list of all servers that contain a DPM 2007 agent. Select the check boxes corresponding to the objects that you want to protect. If you look at Figure 1, you'll see that you have the option to back up shares, volumes, system state and Exchange storage groups. Depending on how your network is configured, you may have other options as well. DPM 2007 is designed to be application aware for many Microsoft products.

You may receive a message informing you that the object you've selected cannot be protected because the required software is missing. If you receive this message, install hotfix 940349 onto the server that you want to protect. There may be other software prerequisites, depending on the type of data that you're trying to protect. After you install the hotfix, go back into the DPM 2007 Administration Console and select the Management tab, then the Agents sub tab. Finally, click the Refresh Information link, found in the Actions pane so that DPM 2007 can acknowledge the prerequisite software. About the author: Brien M.
