I have a need to share files between sites for two different companies that would like to share employees to handle overflow work. These are two different networks several hundred miles apart. My site is Windows 2003 Active Directory. I believe the other site is as well but it may be Novell servers. I would like to have the other site's users log on and access files and work on them as if they were part of our office and vice versa. Is site to site VPN best or would FTP synchronization be better? I was thinking that it would be too tedious to set up the FTP synchronization. I believe that the VPN would allow me to use Active Directory permissions to allow the remote users to map drives, access files and give me complete control as I have with my regular users. FTP to me seems too tedious to configure where I would have to create a separate area to keep the files and rely on the FTP software for security etc. Anyone out there have to set something up like this?
