IIS does support user authentication, using the same user lists as NT security. Because of this, the planning of a site requires careful attention to the accounts used by the Web Server, the RES-Reach software, and end-users. The behaviour of the site may also depend on the configuration of a domain controller. While other Web servers will work on NT Workstation, IIS requires NT Server.
Possible directory structure:
---- MS IIS Server --> Server directory structure
---- HTML files --> html document root
---- Reach
........ Scripts --> contains reach.exe
........ NBT --> contains nbt files, configured as NBTROOT
........ DB --> contains database files
