can you create a package of latest version and upgrade that on a machine locally (don't push it from manager). try it and if it is done sucessfully revert back.

Hi,

As you have mentioned " Nothing happens when I assign install packages to the certain group ( Under CLients - Install packages" - If you have applied package before sometime then it may take some time to upgrade clients.

Thanks guys for your replays.

Chetan, it is now more than 24 hours since the package was assigned - still not updating.

Bijay, I know I can update clients manually - but this is not the case for me doing this for 400 users.

can you check the traffic between SEPM and the targeted clients to know if the packages are being pushed?

I tried to upgrade a client from the Task list on the Home page and it worked OK with the basic package.

Looks like I will have to upgrade all PCs in this way....

Just realized, that updated SEP has Proactive / Network Threat protection dated May 2011 :-(

Hi,

PTP & NTP will also received latest definitions from SEPM.

Autoupgrade should also work, attaching article for same

thanks for the link.

I know how to do it, it is just not working...

Here's some info from our support dB that may be helpful:
