How to fix PowerShell remoting not working

If Powershell remoting is not working between two servers check this:

Check if winrm service is running. Full name is Windows Remote Management (WS-Management)
Execute winrm quickconfig
Enable-PSRemoting -Force command on server.
Get-ExecutionPolicy -List to check that you can execute…
Check that winrm port is the same as listener port
- Winrm port: winrm get winrm/config
- Listener port: winrm enumerate winrm/config/listener
- Change listener port by (from elevated cmd!!!):
  Winrm set winrm/config/listener?Address=*+Transport=HTTP @{Port=”5985″}
Check Windows Firewall is not blocking port.
Check that choosen port (5985 or 81) is open (Cryping, NMap)
Check TrustedHosts list

PowerShell

Get-Item WSMan:\localhost\Client\TrustedHosts Set-Item WSMan:\localhost\Client\TrustedHosts -value * Restart-Service winrm -Force

1
2
3

Get-Item WSMan:\localhost\Client\TrustedHosts
Set-Item WSMan:\localhost\Client\TrustedHosts -value *
Restart-Service winrm -Force
Test with Invoke-Command -ComputerName SERVER -Port 5985 -ScriptBlock {“C:\Program files” | Get-ChildItem}
Test Invoke-Command with Credentials

$server="xxxx"
$remotingPort=5985
$Username = 'yyyy'
$Password = 'zzzz'
$pass = ConvertTo-SecureString -AsPlainText $Password -Force
$Cred = New-Object System.Management.Automation.PSCredential -ArgumentList $Username,$pass
Invoke-Command -ComputerName $server -Port $remotingPort -ScriptBlock {“C:\Program files” |  Get-ChildItem} -Credential  $Cred

$server="xxxx"

$remotingPort=5985

$Username = 'yyyy'

$Password = 'zzzz'

$pass = ConvertTo-SecureString -AsPlainText $Password -Force

$Cred = New-Object System.Management.Automation.PSCredential -ArgumentList $Username,$pass
