Yes, exactly. As far as I know, there's no other way. And all other systems work with it well without any troubles. This error is happening on only one machine and is 100% reproduceable after re-installing of IIS, .NET and PowerShell / IIsProvider.
PS:and yes, I know about IIsConsole.psc1, and I believe it's equivalent to Add-PSSnapin in that regard. (And it doesn't work, as you may guess).
