Software Updates Error: Failed to download content id 16808472. Error: Invalid certificate signature

Hello,

We get an error whenever we try to download updates for a defined Software Update group. See error below;

Our current environment is consists of SCCM 2012 SP1 running on multiple Windows 2012 servers, and a SQL 2012 database. Additionally, we do not use a proxy for any internet traffic.

This issue is consistent for both of our development and production environments when attempting to download Software Updates from Microsoft. There is no consistency with respect to which update that the download fails on, and it happens for large Software Updates Groups and small ones alike.

Have you seen this error happen before? Looking for a solution.

Thanks,

Bill & Brent
