Windows credentials failing on some servers

[Rawel]

Hi There,

On few of our servers the Windows credentials are failing and we get error "Adding target to blacklist. No valid credential found for type [Windows]".

When we check credentials it says "Authentication Failed", but we have checked the event logs and can see that the login happens on the target server.

We are able to discover the same server from our Dev environment with same credentials.

We are able to run the WMI commands from mid server using PS and are getting the desired output.

We have tried adding the target server into trusted hosts as well, but no luck.

Anything else we can try here?

Thanks in Advance !

Thanks all for the replies.

We compared our mid-server configuration for Prod & Dev and found that we had a parameter added in Prod for using WinRM as Windows protocol. Using WMI resolved the issue (though this is not an acceptable behavior, will work with Support team).
