The SEPM has signatures dated 10/23 -- Rev 001. Are those the latest available? I have a handful of clients with those signatures, but most have older versions as far back as 9/11. Clients do have the green dot. SEPM runs on Server 2008R2 Standard.
We are using the default liveupdate policies for both settings and content. I double checked, and the policy does specify to get updates from the management server, and the content settings are all set to latest available.
