Why would you want to put exchange in the dmz? If you want external clients to get at their internal e-mail then place owa in the dmz and pop holes in the firewall to your exchange server.

I am not a guru or anything but i don't think you would be able to if you were outside the network. you'd have to enter all your users in the external box as well. _________________________________ Michael Boggan Network Engineer/Citrix Admin Virtual Desktop Inc.
