Original question here:
Windows Authentication doesn't work with IIS Express 10
At my workplace, we do development on a production network, meaning we have a regular, restricted account and an "admin" account, which has greater rights. We recently had a hardware refresh where we went from Windows 7 to Windows 10, and VS 2013 to VS 2017.
Under the old system, I could log in with my regular account, run VS 2013 as my admin account, and I was able to build and run my web application just fine in Firefox.
This does not work under Windows 10. When I try running VS 2017 under my admin account while logged into my regular account, windows authentication fails, giving me either 401.1 or 401.2 errors. The only way I have been able to get everything working is to log into my admin account and run it from there. This isn't the preferred way to do things. So, is there any way to do what I want to do in Windows 10 and VS 2017?
