Well, still struggling. First off the file I downloaded to be sourced had strangely formatted double quotes so that prevented the file from being interpreted correctly. Fixed that easily with a quick find/replace.
Secondly, the share that I was running these from appear to not have the appropriate permissions and I had to add in the -ExecutionPolicy Bypass which I completely overlooked the ability to set those options with the GUI (very nice!).
What I ended up with was putting the file to be sourced in the ps1 that has the resolution I’m looking for and uploading that as a snapin. It runs perfectly fine when I manually download and run on the workstation but it is still giving me an error when running as a FOG snapin.
