You must open port 5718 to enable communication with the agent coordinator and port 5719
to enable communication with the protection agent.
Installing Protection Agents
• Before you install protection agents on the computers you are going to protect, you must
apply hotfix 940349. For more information about this hotfix, see Microsoft Knowledge Base
article 940349, " Availability of a Volume Shadow Copy Service (VSS) update rollup package
for Windows Server 2003 to resolve some VSS snapshot issues "
(http://go.microsoft.com/fwlink/?LinkId=99034).
After installing Knowledge Base article 940349 and then restarting the DPM server and/or the
protected server, we recommend that you refresh the protection agents in DPM
Administration Console. To refresh the agents, in the Management task area, click
the Agents tab, select the computer, and then in the Actions pane, click Refresh
information. If you do not refresh the protection agents, Error ID: 31008 might appear
because DPM refreshes the protection agents only every 30 minutes.
• If you are installing a protection agent and encounter network-related or permissions-related
issues because of domain policies, we recommend that you install the protection agent
manually. For information about manually installing a protection agent, see Installing
Protection Agents Manually (http://go.microsoft.com/fwlink/?LinkId=100443).
Clustered Data
• You must install the protection agent on all nodes of the server cluster to successfully protect
the clustered data. The servers must be restarted before you can start protecting data. This
restart is necessary to ensure that the protection agent is installed correctly. Because of the
time required to start services, it might take a few minutes after a restart is complete before
DPM can contact the server.
DPM will not restart a server that belongs to Microsoft Cluster Server (MSCS). You must
manually restart a server in an MSCS cluster.
Starting and Configuring the WSS Writer Service
• Before you can start protecting server farms on servers running Windows SharePoint
Services 3.0 or Microsoft Office SharePoint Server 2007, you must start and configure the
Windows SharePoint Services VSS Writer Service (WSS Writer service).
If your Windows SharePoint Services farm has multiple Web Front End (WFE) servers, you
must select only one WFE server when you configure protection in the Create New Protection
Group Wizard.
You must rerun ConfigureSharepoint.exe whenever the Windows SharePoint Services farm
administrator password changes.
