I have a custom package called CST that utilizes the PackageBoot framework. WSUS 3, Patch Manager 1.80 On about half of my systems organization wide it installed perfectly.
The other half it doesn't show up at all in the WSUS logs. If I purge the cache (either via script or in the Patch Manager console) it will pull down and install without issue.
Is there another ready way for me to do clear up this behavior? A lot of the systems in question are rarely in the office so purging the cache is problematic.
I have seen this behavior with some versions of Java. Clearing the local cache on the workstation does sometimes fix the issue for installing Java.
