I have a strange situation here, we have an all Microsoft network with a Cisco 1700 router and Netscreen firewall connected to our ISP over a pair of T1 lines. We are running Microsoft exchange 2000 and are using Microsofts VPN/RRAS server for network connection over the internet for remote users. We have only 2 Mac powerbooks in the entire company and they both have entourage installed. The remote users who have Microsoft based laptops must VPN in before outlook can make connection to the mail server. For some reason the 2 Macs can connect to the exchange server and get mail with just an Internet connection. Any Ideas on why this maybe happening and what I can do about it?
