Environment
- SEPM 14.0 and newer
- All SEP client builds.
Cause
The Prevent clients from downloading full definitions packages option is enabled on the Symantec Endpoint Protection Manager server, which causes the response "HTTP/1.1 400 Bad Request" from the SEPM server in the sylink.log.
Resolution
Disable the Prevent clients from downloading full definitions packages option on the SEPM server from:
- Click on Admin tab
- Click on Servers
- Click on the Server Name under Local Site ()
- Click Edit Server Properties under Tasks
- Click on the Full definitions Download tab.
Note: Enabling Prevent clients from downloading full definitions packages setting does not stop current downloads, but it does prevent any future downloads. If you enable this setting, make sure that you let your clients get protection updates from a LiveUpdate server. Otherwise, your clients do not get any updates.
