WebAdministration Not Loaded Correctly on Remote

When making remote calls that use the WebAdministration module you can sometimes get this error, inconsistently:

ERROR: Get-WebSite : Could not load file or assembly ‘Microsoft.IIS.PowerShell.Framework' or one of its dependencies. The system cannot find the file specified.

It’s a really tricky error because its inconsistent. But, there is a workaround that will prevent the error from giving you too much trouble. From the community that has done troubleshooting on this, the problem seems to occur on the first call that uses the WebAdministration module. If you can wrap that call in a try/catch, then subsequent calls will work correctly.

$scriptBlock = {
    Import-Module WebAdministration

    try {
        $sites = Get-WebSite
    } catch {
        # http://help.octopusdeploy.com/discussions/problems/5172-error-using-get-website-in-predeploy-because-of-filenotfoundexception
        $sites = Get-WebSite
    }
}
