Visualize Active Directory Site Connections

In this post I use powershell with graphviz to create an Active Directory diagram of all site connections between servers. Additionally, I’ve included some code which displays site connection options. You may be able to use this to find isolated DCs or just to see a pretty diagram.

Find Disabled Users With Lync Enabled Without Lync Cmdlts

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).

Gather Remote Command Results With Powershell

Send a remote command using wmi, alternate credentials, and multiple runspaces then retrieve the results serially using mapped secure channels to the remote host. The remote command execution function supports custom timeout parameters in case of wmi problems and returns the remote tmp file information containing the command results. You can view verbose information on each runspace thread in realtime with the -Verbose option.
