Restoring client-server communication settings by using the SylinkDrop tool

The Sylink.xml file includes communication settings between the client and a Symantec Endpoint Protection Manager server. If the clients have lost the communication with a management server, you must replace the old Sylink.xml file with a new Sylink.xml file. The SylinkDrop tool automatically replaces the Sylink.xml file on the client computer with a new Sylink.xml file.

Note:

You can also replace the Sylink.xml file by redeploying a client installation package. Use this method for a large number of computers, for computers that you cannot physically access easily or computers that require administrative access.

See Restoring client-server communications with Communication Update Package Deployment.

When you run the SylinkDrop tool, it can also perform the following tasks:

  • Migrates or moves clients to a new domain or management server.

  • Restores the communication breakages to the client that cannot be corrected on the management server.

  • Moves a client from one server to another server that is not a replication partner.

  • Moves a client from one domain to another.

  • Converts an unmanaged client to a managed client.

You can write a script with the tool to modify communication settings for large numbers of clients.

See About managed and unmanaged clients.

See Troubleshooting communication problems between the management server and the client.

Note:

You must disable Tamper Protection to use the SylinkDrop.exe tool. You can also create a Tamper Protection exception for the SylinkDrop.exe tool.

See Changing Tamper Protection settings.

See Creating a Tamper Protection exception on Windows clients.

To recover client-server communication settings by using the SylinkDrop tool for Windows

  1. In the console, export the communications file from the group that connects to the management server to which you want the client computer to connect. The communications file is the Sylink.xml file.

    See Exporting the client-server communications file (Sylink.xml) manually.

  2. Copy the communication file to the client computer.

    You can either save the file to a network location, email it to the user on the client computer, or copy it to removable media.

  3. Do one of the following tasks:

    • On the Tools installation file, locate \Tools\SylinkDrop\SylinkDrop.exe.

    • On the computer that runs the management server, locate drive:\Program Files (x86)\Symantec\Symantec Endpoint Protection\Version.Number\Bin\SylinkDrop.exe

    You can run the tool remotely or save it and then run it on the client computer. If you use the tool on the command line, read the SylinkDrop.txt file for a list of the tool's command parameters.

  4. In the Sylink Drop dialog box, click Browse, and locate the .xml file you deployed in step 2 to the client computer.

  5. Click Update Sylink.

  6. When you see a confirmation dialog box, click OK.

  7. In the Sylink Drop dialog box, click Exit.
