time/date user was added to group

Hi, I'm very new here.
How can I find when a user was added/subtracted from a group?
Can I create a report of when all users in a group added/subtracted?
Many thanks for any help.

There's no field that stores that information. You may be able to find this out, though, by searching the Security events on your domain controllers. In Hyena you can right-click on a controller, or selection of controllers and choose Events->Filter Events. Choose the Security log and then enter in the criteria to search on and see if anything comes up.
