Windows Servers have limitations on maximum connected users and maximum open files per session. These are default settings:

  • Maximum Logged On Users: 16777216
  • Maximum open files per session: 16384

You can view them with net config server command.

    Those limits apply to network access to files: not local (including within a remote desktop session).
