Azure-pipelines-agent: TF400813: Resource not available for anonymous access

[Arenoros]

Agent v2.164.0
Log: Agent_20200101-215536-utc.log

TFS version: 17.153.29522.3 (AzureDevOps2019.Update1.1)

I tried enable all type auth in iis

I looked at all the links that I found in Google: #1500 #2214 #1839 #759 #2565

What am I doing wrong?

I am having the exact same issue. If I use negotiate and pass in a username and password the agent installs correctly however if I use a pat it gives:

TF400813: Resource not available for anonymous access. Client authentication required.

Use "https://[servername]/[organizationname]"

@alexanderwieland's solution worked for me. Bizarre that it works without the collection/org name on a Negotiate but not with a PAT...and that there's no obvious documentation of this.

I had the same issue with an OnPrem Azure DevOps Server 2019 Update 1 and tried different things, but my college finally noticed, that the UI was missing an important part.

The fix: Our Azure DevOps Service account needed __write__ permissions on this directory:

C:\ProgramData\Microsoft\Crypto\RSA\MachineKeys
