I have followed this before. http://support.microsoft.com/?kbid=272198 Microsoft has a web-based version of GALMOD that suffers from many of the same limitations as the Windows version, but at least it is easier to deploy. And it is free. See KB 242223 - http://support.microsoft.com/?kbid=242223. Good luck. Timo Timo Vasquez- D.S.S.

Hi all, My supervisor has asked me to come up with a way to allow certain users in our office the ability to change some attributes of the GAL, such as users telephone numbers. What is the best way to do something like this? I'm considering a taskpad of AD Users and Computers; but then, I guess I would need to install Exchange System Manager on any machine that was going to be used to make these changes? That doesn't strike me as a particularly elegant or secure solution. Any thoughts or alternatives would be much appreciated. Thanks, --Al Puzzuoli
