OT: Merging two Active-DirectoriesHi All I am considering exposing my exchange server (SBS2000) onto the Internet. I have a few users (remote users) who would really benefit from being able to connect Outlook to exchange and access the shared folders/ calendars etc. I am wondering whether to purchase and set up a VPN with the users or simply open ports on the firewall to the exchange server. All comments greatfully received. Frustrated Admin
