New-PSSession does not work locally

Question

I am trying to connect to the localhost using New-PSSession.

I have

• Configured WinRM using

  winrm quickconfig
  

• Enabled PS Remoting

  Enable-PSRemoting
  

• Added Trusted Host

  Set-Item WSMan:\localhost\Client\TrustedHosts * -Force
  

• There is an inbound rule on 8173 port on firewall.

Output of winrm:

PS C:\> winrm get winrm/config/listener?Address=*+Transport=HTTP
Listener
    Address = *
    Transport = HTTP
    Port = 8173
    Hostname
    Enabled = true
    URLPrefix = wsman
    CertificateThumbprint
    Listening on = 127.0.0.1

I am trying to run the following command:

New-PSSession -ConnectionUri http://localhost:8173/WSMAN

but I get this error:

[localhost] Processing data from remote server failed with the following error message:
Error with error code 14 occurred while calling method WSManPluginReceiveResult. For
more information, see the about_Remote_Troubleshooting Help topic.
    + CategoryInfo          : OpenError: (System.Manageme....RemoteRunspace:RemoteRunspace) [], PSRemotingTransportException
    + FullyQualifiedErrorId : PSSessionOpenFailed

EDIT:

The only extra thing that I see is that the network is connected to public $listenerport = "8173" winrmwinrm create winrm/config/Listener?Address=*+Transport=HTTP "@{Port="$listenerport"}"

Answer 1

By process of elimination, we can rule out firewall as an issue, as you are only connecting to the loopback address (127.0.0.1). We can also rule out WinRM configuration which looks fine.

The error message suggests that TCP connection to http://localhost:8173/WSMAN is actually successful, but fault occurs while establishing PS session.

This points to Microsoft.PowerShell session configuration.

Looks like there is a discrepancy in the permissions you see when looking at

Set-PSSessionConfiguration -Name Microsoft.PowerShell -showSecurityDescriptorUI 

and the permission actually assigned to Microsoft.PowerShell. The output of

Get-PSSessionConfiguration microsoft.powershell | fl *

should have the "SecurityDescriptorSddl" and "Permission" proprieties listed. Like this:

Name                   : microsoft.powershell
Filename               : %windir%\system32\pwrshplugin.dll
SDKVersion             : 1
XmlRenderingType       : text
lang                   : en-US
PSVersion              : 2.0
ResourceUri            : http://schemas.microsoft.com/powershell/microsoft.powershell
SupportsOptions        : true
Capability             : {Shell}
xmlns                  : http://schemas.microsoft.com/wbem/wsman/1/config/PluginConfiguration
Uri                    : http://schemas.microsoft.com/powershell/microsoft.powershell
ExactMatch             : true
SecurityDescriptorSddl : O:NSG:BAD:P(A;;GA;;;BA)S:P(AU;FA;GA;;;WD)(AU;SA;GXGW;;;WD)
Permission             : BUILTIN\Administrators AccessAllowed

Try removing and reassigning these permissions.

EDIT:

Based on the information you have provided this is not the main problem. I have also noticed that you have a non standard "RootSDDL" in WinRM service settings.

RootSDDL = O:NSG:BAD:P(A;;GA;;;BA)S:P(AU;FA;GA;;;S-1-5-21-2458768215-3945602940-3262220185-1045)(AU;SA;GWGX;;;WD)

by default this should be

RootSDDL = O:NSG:BAD:P(A;;GA;;;BA)S:P(AU;FA;GA;;;WD)(AU;SA;GWGX;;;WD)

I have recreated this on the test VM and Remoting still works. So I had another look at your WinRM configuration ...

Solution

Your problem is this line

MaxEnvelopeSizekb = 1039440

By setting this value I can replicate the issue you have. I would suggest to set this to something more reasonable, or to default.

winrm set winrm/config '@{MaxEnvelopeSizekb="150"}'

Will fix your problem.
