Hi,
1. Log in to SEPM, go to client group where the GUP client is in. Add a sub-group.
2. Move the GUP client to the sub-group.
3. Check off the inherit checkbox for the sub-group, configure the “communication setting” to be in pull mode and put a short-time heartbeat there, maybe 5 mins.
4. if have more GUP clients, repeat 1-3.
If above suggested steps not helped then create a case with Symantec & PM me the case number.
