Visualize Active Directory Site Connections

Here is a quick tip which applies to more than just Lync. I use powershell with .NET ADSI to gather a list of all users which are disabled but still have Lync sip addresses assigned. There are numerous reasons to disable lync on such accounts. One reason would be to make certain that users whom are no longer with the organization get removed from the Lync address list. Another is so these same users can no longer access Lync! (Yes, a disabled AD account may still be authorized to access Lync).
