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). – Richard Mar 20 '11 at 11:35
