Output System.Object

[tinakane]

When I ran this against a domain with all Server 2016's the output was fine.

When I run this against another domain with a mix of 2016/2012 non R2 I get output at the bottom "System.Object" - since that isn't translated to a DC name is this bad output, an error in syntax or is this to be expected?

Example,

At line 425:

    $compare | ForEach-Object {
        $DC = $compare.Inputobject

It's doing a "foreach" on the whole array, leading to every item being a System.Object[] to log. This specific issue can be fixed by changing 426 to:

        $DC = $_.Inputobject

But that that continues to log each server as having no KB installed directly after stating that it did. I don't believe Compare-Object has the semantics that it's being used for here.
