MS Azure DevOps Server: No Agent Pool details visible when clicking on the Agent Pool

Question

Environment: Azure DevOps Server 2022 19.225.34309.2 (AzureDevOps2022.1)

I am prototyping an MS Azure DevOps Server on-premises setup. No issues installing the product until it came to the creation of Build Agents.

I can see the Default Agent Pool:

However, I see no pool details when I click on it:

My account is a Collection Administrator:

No error messages and the DevOps portal continues to operate normally.

I am expecting to see pool details when clicking on the pool, including seeing the Agents tab and being able to choose "New Agent" like it is described here: Download and configure the agent

I’ve tried to access Agent Pool details through Project Settings with the same result. I have also created another agent pool: the newly created pool would be seen in the pool list along with the Default Pool, but no pool details would be shown if clicked on it.

I've checked the IIS Anonymous Authentication setting as @kevin suggested below. It was already set as Kevin suggested on the site level. Setting it to "Application Pool Identity" at the server level also did not help. Here are results of IISReset.

Browser console output

Can you please help me resolve the issue?

Thank you!

Answer 1

The issue could be related to the IIS Configuration of the Azure DevOps Server.

Refer to the following steps to change the Anonymous Authentication to Application pool identity and check if it can work.

1. Open IIS Manager (inetmgr)

2. Navigate to Sites > Azure DevOps Server

3. Double click on the Authentication icon

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

5. Change it to Application pool identity.

   For example:

   

6. Use Administrator CMD to run the IISRESET command.

Then you can navigate to the Agent Pool Page and check if the details will show.

Update:

You can refer to the following steps to grant the Azure DevOps Server User Impersonate a client after authentication permission.

1. Open Local Security Policy editor.
2. Navigate to Security Settings>Local Policies>User Rights Assignment
3. Double click on Impersonate a client after authentication
