Making Sure ConfigMgr Task Sequence Has All The Packages It Needs To Continue
From the archive (2010). Written for the tools of the time, so some details may be out of date.
Michael Niehaus posted a blog post with some powershell scripts to help identify what packages you might be missing for your TS. This can be a frustrating process as you try to identify what packages are missing, since the generic error doesn’t tell you what is all actually missing, just that something IS missing (one at a time). :)
Script files are attached to his post located here.
