Windows Start menu layout.xml - Image location

Question

Hello,

We are using a layout.xml file on our DC server that is pushed to each PC via group policy. This was working previously however there is an issue with the image file we are calling. I have no idea why some PCs are able to load the image and some are not, its extremely inconsistent, even if the same user uses the same PCs, and those PCs are all receiving the same group policies.

In our script we have: Wide310x150LogoUri="ms-appx:///Assets/310x150bg.png"

This file is in our DC Servers NETLOGON/Images folder. I have read through all of Microsoft's documentation, and forums for a few hours and cannot work out how I can check that this path to the file is correct, or if it working. The path doesn't work in a browser, or explorer, the policy that applies the layout.xml doesn't have any options for setting any paths other than the layout.xml itself.

Help would be appreciated.

Thanks, Corey
