TFS2017 On-Prem - Build Web page is blank & images not showing

Question

There are a few cosmetic issues with a TFS server I've setup.

The Builds Page is blank and the images aren't showing:

The entire strip where the Build Definitions are displayed should look like this:

A less obvious problem is the images are not showing.

Does anyone know whats causing this? or how to troubleshoot it?

Note: All the other pages show up fine, Releases, Packages, Library & Task Groups, its only Builds that's missing.

Answer 1

I found this MSDN thread for the missing images:

1) Open IIS Manager (inetmgr)

2) Navigate to Sites > Team Foundation Server

3) Double click on the Authentication icon

4) Right Click on Anonymous Authentication and select "Edit..."

5) Anonymous user identity is normally set to IUSR. Change it to "Application pool identity".

So I did that:

And now the Build Definitions showing, but the images are still not showing. Its so weird how running a fix for images (symptom) fixed the root cause, but the symptom is still not fixed.

Edit:

After a IISRESET the images are now showing properly. Also note that a Build Agent I had setup and registered to a AgentPool was not showing either until I applied this fix.

ps:

The other thing I didn't try is setting the SPN for the service account:
