Getting quick info from systems

One thing that is pretty common when you get to a new customer is that they usually have no clue what systems they actually have on their network.
In most cases not all servers are members of AD so that is the reason I use an input list instead of getting all the computer objects from AD and then filter on OS, or specify a "top" OU and then search all computer objects from that OU and then all sub-OUs. This can of course be easily changed in the below script to do just that if you want, I might even post how to do it later... :)

The second thing is that when I wrote this, I actually just needed the info to be showed on the screen. Which is why I didn't created an output file and saved it directly to it (here I just pipe it). I will post a function how to create an output file later and the below script can easily be changed for this as well.


Do note that I couldn't get proper formatting (especially TAB) in this post so the script might look a bit strange. Also note that line breaks are not always correct, so test it first in your lab! I take NO responsibility for the script and it is your responsibility to test it in a lab environment!
