I've been working today trying to deliver to one of my Clients Active Directory documentation. To my surprise, something that worked fine for a very long time has started to provide weird results. So, after spending about 8 hours taking apart a few of my PowerShell modules trying to find out what is wrong finally, I've found it: Export-CliXML / Import-CliXML were behaving in a way I didn't expect them to. But let's start from the beginning, shall we? Those two commands are great. I've used them multiple times with great success (or so I thought). It all started with the following Word Table showing 1 and 0 in places where I've expected Domain Local or Universal Groups, and I had no clue where to look, as most of my tests were working great, just this one customer data was delivering some weird results.
