Error! 401/Unauthorized. Possible causes: - Invalid credentials

[OrnaldoNaqellar]

Hello,

I'm  facing a problem today with two of my servers that are not in domain. The password and the username of the local user we are using is OK. Attach are the setting of event sources i have configured.

winrmconfig.ps1 powershell script is configured successfully and the listener is up:

The error is the following:

Error! 401/Unauthorized.
Possible causes:
- Invalid credentials.

Please any help ?

Thank You

Hello  Ornaldo,

Kindly run the following command on the Windows Machine and try again the test connection.

winrm set winrm/config/service/auth '@{Basic="true"}'

The command should be execute via cmd or powershell ?

[YoussefMadkour]

You can run the command on CMD

I have invalid command

You can run it on PS as the following

PS C:\Users\Administrator.2K8R2-DC> winrm set winrm/config/service/auth '@{Basic="true"}'

Auth

    Basic = true

    Kerberos = true

    Negotiate = true

    Certificate = false

    CredSSP = false

    CbtHardeningLevel = Relaxed

PS C:\Users\Administrator.2K8R2-DC>

Great . It worked on one of the servers

But in the other not

The output is the same:

Basic = true

    Kerberos = true

    Negotiate = true

    Certificate = false

    CredSSP = false

    CbtHardeningLevel = Relaxed

Hi,

after using this command :

winrm set winrm/config/service/auth '@{Basic="true"}' 

run again the PS:

Powershell -command “c:\temp\winrmconfig.ps1 -Action enable -User mycollectionuser@mydomain.com” it will solve the issue after

Thank You for your replay. I tried the command with no error but still i have 

Error! 401/Unauthorized.

You may also try this from a PowerShell (remember to run PowerShell as administrator)

winrm set winrm/config/service '@{AllowUnencrypted="true"}'

(since you are using both HTTP and Basic)
