For example, a 100-seat license covers up to 100 individual users in a single organization operating either in a shared network environment or as separate users (e.g. for laptops). In a terminal server environment, each terminal server user counts as a separate user. In addition to the number of specified user computers, dtSearch network multi-user licenses cover usage of the software on a single additional machine for indexing and/or a single additional computer for shared network index access. All other installations for either indexing or searching including temporary forensics and e-discovery installations require additional licenses. (Requires Windows)
