SEP 12.1.3 Manager updating virus definitions very slowly using GUPs

Hey,

SEPM with some remote sites set up using GUPs. For the last three days a total of 400 clients out of 1200 have been updated using GUPs. The virus defs on the SEPM are up to date and the 10 GUPs in use are alos up to date with definitions. I can telnet 2967 on all GUPs.

Does anyone know why updating clients from the GUPs is taking so long? It is painfully slow. Some of the links are 2MB but delta updates is all that are going out so I didn't expect it to take so long.

Any ideas from anyone would be appreciated as I have tried everything I can to sort this out. I thought to create a forum thread here before maybe contacting Symantec.

Thanks.
