On the client run PowerShell commands:

cd wsman:\localhost\Client
Set-Item .\AllowUnencrypted -Value $True -Force
Set-Item .\TrustedHosts -Value * -Force

On the server run PowerShell commands:

Enable-PSRemoting -Force
New-ItemProperty -Path HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\WSMAN\Service -Name allow_unencrypted -Value 1 -PropertyType DWORD

On the client switch PowerShell provider to file system and run PowerShell commands to test remoting configuration:

$credential = Get-Credential -Message "Enter credentials" -UserName domain\user
Test-WSMan -ComputerName ServerName -Credential $credential -Authentication Negotiate
Enter-PSSession -ComputerName ServerName -Credential $credential

Note that this configuration is intended only for development or testing purposes and is not intended for production use.
