Unique PermissionError: [WinError 5] Access is denied IIS Issue

Question

I am currently setting up a django site to run on IIS, however I am running into an issue with the USZipCodes python module, When it goes to call the USZipCodes module if gets an access denied error.

I have confirmed all folders regarding this EXCEPT the systemprofile folder has proper permissions for the IIS_IUSRS profile. I would do the systemprofile as well but it just give me more errors and I would prefer not to

This module works fine when not IIS, through CMD it works fine, it is only when using IIS to run the app does this occur.

I suspect I may just have the cut the module out but I would prefer not too

Figured I would follow up. After quite some hours I was able to resolve the issue.

When you setup the IIS, it creates a local group called IIS_LUSRS. You must add the user (local or domain) that you log into to run IIS to this local groups (can be done through the lusrmgr.msc program). Then after this is done, allow that group modify and write privs on the python site package pathlib and the system profile in system 32.

This is not the best solutions, but it fixed it for me...
