To configure a firewall on a file server, you must open port 135 to TCP traffic, and you must enable the file agent (Msdpmfsagentca.exe) to communicate through the firewall.

Before you can install, uninstall, or upgrade a file agent on a file server that has a firewall enabled, you must first disable the firewall. After that, you can install, uninstall, or upgrade a file agent by using DPM Administrator Console, and then re-enable the firewall.

The following procedures apply to the Windows Firewall configuration. For instructions on configuring other firewall software, consult the firewall documentation.

To re-enable and configure Windows Firewall on a file server
