DLO is designed to work in firewall environments. For DLO to function properly in a firewall environment, network file shares must be visible after establishing a remote connection such as VPN. If file sharing is not allowed, DLO will not be able to transfer files to or from the network user data folder. Desktop computer files will still be protected to the desktop user data folder, and will be transferred when the network user data folder is accessible. 



Before installing DLO to remote computers, the following must be considered:





Windows XP/Windows Server 2003

To push-install to a Windows XP/Windows Server 2003 computer, you must enable File and Printer Sharing on the Windows Firewall Exceptions list for the following ports:

  • 135 (RPC)

  • 445 (TCP)

  • 103X (mostly 1037)

  • 441 (RPC)

For more information about the Windows Firewall Exception list, refer to the Microsoft Windows documentation.

During the installation process, the Remote Launch and Remote Access security permissions are set for the Administrator’s group.

You should enable the “Allow remote administration exception” group policy for the computer to which you push the installation.

SWindows Vista/Windows 7/Windows Server 2008

To push-install to a computer that runs Windows Server 2008, you must enable certain items on the destination computer’s Windows Firewall Exceptions list. You must enable the following items:

  • File and Printer Sharing

  • Windows Management Instrumentation (WMI)

For more information refer to the Microsoft Windows documentation.

Symantec Endpoint Protection (SEP)11.0 or later To push-install DLO to a computer that runs Symantec Endpoint Protection (SEP) version 11.0 or later, you must configure SEP to share files and printers. The file and printer sharing feature is turned off by default.
