I have built a new one and have it online and running. Is there a way to tell if any servers are using the old one for authentication on the BDC itself. Instead of going to each server. I want to bring the old one down but don't want to cause login issues if I do. _________________________________ Michael Boggan Network Engineer/Citrix Admin Virtual Desktop Inc.
