Hey Josh,
My point is 1st tier support should be working through the troubleshooting steps, either remoting into client environments when tickets come in, or better yet, trying to reproduce in their own test environment. It's crazy to me the immediate answer from support is to send an email to "check this TECH article, it has a bunch of steps, let me know the results."
If our first level support at my company did that when tickets came in, they'd be getting bad reviews and looking for another job. It certainly serves the purpose of making customers not want to put in tickets anymore.
But, don't get me wrong, I appreciate you taking the time to try to help here on Connect as always. To answer your questions
<<The KM: TECH167291 is in order, for if the update is installed on the client, and the Client's Resource Manager > View > Inventories > Data Class > Software Management > Patch Management; review the IsInstalled Dataclass. If that update is listed, the raw IsInstalled Rule=TRUE and the problem is the Reboot Event is missing for that update.>>
KB2908783 is not listed for a computer that got the update from patch.
From STPatchassessment.xml
"Item Status="Missing" PatchName="Windows6.1-Windows7-SP1-KB2908783-x86.msu" Superseded="false" SQNumber="Q2908783" BulletinID="MSWU-921" Class="Patch" Reason="File version is less than expected. [C:\Windows\SYSTEM32\DRIVERS\MSISCSI.SYS 6.1.7601.17514 < 6.1.7601.22589]"
I looked http://support.microsoft.com/kb/2908783 and http://www.microsoft.com/en-us/download/details.aspx?id=42348 and cannot find what the expected/correct version of that file should be under file details, i must be missing it. I assume it should be .22589, but it's not.
<<Lastly, if the update is installed in Add/Remove, and not listed in the IsInstalled Patch Dataclass, and the file is not current per the vendor site>>
This seems to all be true.
<<The method detailed above in my early comment is the correct process moving forward.>>
I uninstalled the update from add/remove programs and let patch reinstall. It was successful, but the MSISCSI file version didn't change. Rebooted, ran assessment scan again and STP has same message.
The failed update is happening on all of our workstations, not just a few .
