Having multiple DMZ's helps in this situation. One DMZ could be for the external facing services. Another could be for domain controllers that the external servers need to authenticate with. While your at it, throw in a database DMZ, wireless DMZ, remote access DMZ, management DMZ, etc... The more DMZs you have, the more granular access controls you can enforce. Mitchell

We are in a situation where we are currently planning the move of our web server from an externally hosted solution to hosting the web server in house. As part of this move we will be implementing a new internal application that will run on the web server that will require authentication based on Active Directory account info. Obviously this will require that the web server has the ability to communicate with the AD domain controllers. That being the case will it still be possible to place this web server on a DMZ or will the amount of open ports required between the DMZ and LAN for the required authentication process severely mitigate the benefits of placing the server in the DMZ in the first place? Any and all suggestions and or strategies to accomplish this in the most secure fashion are welcome and appreciated. Thanks!
