When troubleshooting content delivery, you will first need to determine if the issue is likely with the Symantec Endpoint Protection Manager (SEPM) (eg. all clients cannot update), Group Update Provider (GUP) (eg. all clients going to a single GUP cannot update) or clients (eg. some clients cannot update). The following document may assist troubleshooting.

If the issue appears to be with the SEPM:
- Verify the SEPM has the updated definitions. See the following document
LiveUpdate and content troubleshooting for the Symantec Endpoint Protection Manager
http://www.symantec.com/docs/TECH105924
- Verify the SEPM is set to download the specific content. In the SEPM, this can be done via Admin > Servers, right click Local Site > Edit site properties. On the LiveUpdate tab under "Content Types to Download" click "Change Selection" and verify the specific content type is checked.
- Verify the LiveUpdate policy for the specific group is set to allow the latest content of the specific type. See the following document

- Enable debug logging on the SEPM, run LiveUpdate and check the logs for errors. See the following document

If the issue appears to be with a GUP:
- Verify in the SEPM that the LiveUpdate policy the clients have specify to use a GUP.
- Verify in the SEPM that the LiveUpdate policy the GUP has specifies that it is to be a GUP.
- Check that the GUP knows it is a GUP and that it is listening for connections. See the following document
