Hello.
I've been using the same GUP's for about two years now with no problems to speak of. However, I've recently noticed that the SharedUpdates folder no longer resides in the default location of:
C:\Program Files\Symantec\Symantec Endpoint Protection\SharedUpdates.
My SEPM is running on version 12.1.4013.4013 Clients are mostly one version behind. I'm not sure but could it be that the location has changed with the recent upgrade of SEPM as this would co-inside with my theory. Please tell me if I'm barking up the wrong tree.
A separate issue but related; I've also had an issue for quite some time trying to update remote clients across a low speed WAN connection, so much so that a firewall rule is in place to stop network traffic to and from the GUP during business hours. I assume that outside business hours the GUP can and will request all the required updates and distribute them when the clients may a request.
I apologise for my basic explaination and terminology but if I need to explain anything further let me know.
Thank you in advance
