Of all the clients that are not updating, do they belong to a certain group or location in your SEPM? Are these clients able to communicate and receive policy updates from the SEPM?
No they do not belong to a certain group, but to all groups. The few clients who are up to date (less than 10%) also do not belong to a certain group.
Would it also be possible for you to post a SEP Support Tool from the SEPM?
I included a print screen of the results of SEP Support Tool on the SEPM. There was one error, I do not know if this can be something.
It would be interesting to see how the LiveUpdate policy is set up. Please also provide the name of the group and/or location where these clients seem to be failing.
I included the print screens of the LiveUpdate policy. All clients in the groups which you can see in the print screen are failing. The clients which are not failing, are getting up-to-date.
Are you using any GUPs or LiveUpdate Administrator to distribute content or just SEPM? Are you using any kind of a proxy in your environment?
We do not use GUP or LiveUpdate Administrator for distribution, only SEPM. We use a proxy (TMG), but the SEPM do not use proxy, it has a direct connection to outside.
