Confusing Powershell behavior - powershell

Question

Am a bit confused w/ remote executing a powershell command. I have a test server (Win 2k8-R2-SP1) called ServerA, which has powershell remoting enabled correctly. From my dev machine (Win 2k8-R2-SP1), am able to remote execure powershell commands correctly.
But, when I try to execute the same command from a different server called ServerB (Win 2k8-R2), I get the following error
[ServerA] Connecting to remote server failed with the following error message : The client cannot connect to the destination specified in the request. Verify that the service on the destination is running and is accepting requests. Consult the logs and documentation for the WS-Management service running on the destination, most commonly IIS or WinRM.
If the destination is the WinRM service, run the following command on the destination to analyze and configure the WinRM service: "winrm quickconfig". For more information, see the about_Remote_Troubleshooting Help topic.
+ CategoryInfo : OpenError: (:) [], PSRemotingTransportException
+ FullyQualifiedErrorId : PSSessionStateBroken
All three machines are in the same domain. My confusion is that from my dev machine, I am perfectly able to connect to ServerA and execute the command.
Will the fact that ServerB does not have SP1, make a difference? Please advise. I am using the same domain account which has admin rights on all 3 servers.
And the command that I am trying is
Invoke-Command -ComputerName ServerA -ScriptBlock {Get-UICulture}.
Please help.
Thanks

Answer 1

Run winrm quickconfig or Enable-PSRemoting -force from ServerB.
Verify service is running with get-service winrm

Also, run this from your local dev box:
Set-Item WSMan:\localhost\Client\TrustedHosts -Value "*" -Force

Answer 2

I've had this same problem as well, on a machine that was working for remote powershell in the past. In my case the solution was to clear the Security Log. It was full, and I believe this was preventing powershell from making a proper secure connection.

Answer 3

The following fixed my problem:
You either have to empty your iplisten list which can be checked using the following CMD command:
netsh http show iplist
or to add the loop back address to it if there is any other addresses:
netsh http add iplisten 127.0.0.1

I was having this same issue and resolved in the following way. Running
winrm quickconfig
returned the below error.
winrm : WSManFault

In my case, this was a virtual NIC for a hypervisor service I was running on my machine. Once I changed this to Private, winrm quickconfig ran without error. I still had issues connecting to some machines and getting the same failure as described in this thread. To resolve, I checked for and started the winrm service where it was stopped.

To save having to enable WinRM on every single server you manage, you can run this batch script:
Requirements:
A text file with all the servers you wish to enable WinRM on
PSExec in your Windows\System32 directory, downloaded from: https://technet.microsoft.com/en-us/sysinternals/pstools.aspx?f=255&MSPPError=-2147217396
Powershell on the server you're connecting to
Usage: EnablePSRemoting.bat PCs.txt
#echo off
for /f %%f in (%1) do (
psexec.exe \\%%f -accepteula -h -d -s powershell.exe "enable-psremoting -force"
echo Enabled on %%f
)

Answer 6

I have been looking for the answer for days and I found the issue;
It seems that the IIS 7 .NET Extensibility component was not installed causing this issue. We have a 2012 R2 Exchange 2010 server;
https://technet.microsoft.com/en-us/library/dd421841(v=exchg.80).aspx
I installed it by entering this in powershell;
See here the prerequisites for Exchange 2010.
https://technet.microsoft.com/en-us/library/bb691354(v=exchg.141)
This Exchange server of ours has only the mailbox role, the other is still CAS and HUB transport;
So we need this command;
Add-WindowsFeature NET-Framework-Features,RSAT-Clustering,Web-Mgmt-Console,WAS-Process-Model,Web-Basic-Auth,Web-Lgcy-Mgmt-Console,Web-Metabase,Web-Net-Ext,Web-Server,Web-Windows-Auth -Restart
The part of Web-Net-Ext installed the IIS 7.NET Extensibility component.
No need to restart.
Just my 2 cents, maybe this helps someone else :-)

Answer 7

In my case, WinRM was not configured correctly. This is what I used to enable it remotely:
$x=Get-WmiObject -ComputerName "<computer name>" -Namespace "root\cimv2" -Class "Win32_Process" -List
$x.Create('C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe -Command "& C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe -Command {Enable-PSRemoting}"',$null,$null)
