We have an Exchange 2003 environment. Most of our remote users use Outlook 2003 on Windows XP SP2 and connect via RPC/HTTPS. We have started to encounter users that are running Windows 2000 and need all the functionality of Outlook. Seeing as the W2K clients don't support RPC/HTTPS that have been out of luck. I have now been charged with the task of making it work. I am looking for any information that woudl assist in the following environment.
Our Exchange is set up as a front-end/backend configuration. The front end server have public IPs that are protected by a firewall. The second NIC in the FE server conencted to the backend servers which all have private addresses. Obviously the BE network, where the AD controllers live also are on private IPs and are not reachable from the public side of the FE server.
What is the best approach to achieve Outlook access to this configuration from W2K machines that are remote?
