When you use a Invoke-Command or New-PSSession Cmdlet you might run into an error stating that the Certificate recovation list could not be checked. When you set the corresponding property

[System.Net.ServicePointManager]::CheckCertificateRevocationList = $false;

– you still get the same error message.

This is because the aforementioned Cmdlets do not honour this setting (whereas they honour

[System.Net.ServicePointManager]::ServerCertificateValidationCallback = { $true; };

to bypass all certificate validation). Instead they implement their own mechanism that you can set via PSSessionOption:

$sOpt = New-PSSessionOption -SkipRevocationCheck -SkipCACheck;

You then pass on this variable to the respective Cmdlet via the -SessionOption parameter.
