Q&A Monday: Determine what Domain Controller authenticated a user


We have many domain controllers in our environment and while working through troubleshooting, I was wondering if there was a way to find out which domain controller logged the user into the network while sitting at the users PC.  The problem ended up not being related, but the question stuck with me, is there a way to tell which domain controller logged a user in?

Carol, there is a very simple way of doing this, all you need to do is open a command prompt and type:

set logonserver


echo %logonserver%

This will show you what server logged the current user in.
