WMI: "Socket Not Connected" when using Microsoft Assessment & Planning Toolkit

Greetings---

I am currently assessing our environment with the Microsoft Assessment & Planning (MAP) Toolkit. 

Of our 100 or so servers, 7 have returned a WMI Status:  Failed - Socket not connected in the InventoryResults *.xlsx output.

This is not a typical WMI error returned via this help page:

I have attempted to run WBEMTEST and I am able to connect to the \\remote\root\cim just fine and query (e.g. select * from Win32_etc)

Any clues?
