Define "Exchange". We put Exchange in the DMZ for OWA. Not a full blown Exchange server with mailboxes and information stores, but a path for attack still. ~~~~~ Paris E.

OK? Hey Karl. The only reason people put Exchange on the DMZ is to act as an SMTP relay whereby this relay will be the middle-man between the internal Exchange server and the Internet. As far as syncing AD in the DMZ I don't think it's recommended as this would defeat the purpose of DMZ which is to hide the internal LAN's resources.

Hello One of the developers I work with has come up with a wild and crazy notion to write a .NET app that sits on a DMZ Web server but gets user information from the Active Directory on the other side of the firewall.. I'm inexperienced with this, so did some research and found that this kind of thing is possible (plenty of articles on putting Exchange servers in the DMZ), but found myself wondering if this ever happens, i.e. do people actually have their networks set up this way? Do folk expose/replicate AD to the DMZ in practice? It's all very well that this stuff is possible, but if it's perceived as insecure and not implementable in the real world . . . . . . .
