The Setup: Server 2008 R2 Enterprise with IIS 7.5 Home connection with dynamic external IP
The Goal: Encrypted passive ftp server with AD integration no client side adjustments (save making sure to use ftpes in their client)
The Problem: I'm running on a home connection with a dynamic external IP and the firewall is apparently doing something screwy
What Happens: It works intermittently (its broken more often than not) The control ports seem to work fine but not the data ports, because it can contact authenticate and its gets all the way to the point where its supposed to pull the Virtual directory
