Unfortunately this is failing on a basic call by Microsoft.Web.Administration ("MWA") to get the configurations on the server, effectively below call to GetSection. The MWA dll is shipped with IIS and is used by both the Migration Assistant GUI and the PowerShell scripts to interact with IIS.

$iisInstallPath = [System.Environment]::ExpandEnvironmentVariables("%windir%\system32\inetsrv\Microsoft.Web.Administration.dll");
        [System.Reflection.Assembly]::LoadFrom($iisInstallPath) | Out-Null; 
        $sm = New-Object Microsoft.Web.Administration.ServerManager;
        $Config = $sm.GetApplicationHostConfiguration();
        $configPathsSection = $Config.GetSection("configPaths")

My understanding is that this type of error could be caused by access issues and/or things like path-too-long (where file paths start to exceed 260 characters) - would either of these scenarios be a possible explanation on this server?

Closing due to lack of activity for over 90 days
