Does Windows Server 2008 R2 have similar limitations to maximum number of opened files like linux have?

Windows does not have such a limit other than memory (both kernel and user). Also open file data structures are shared with other kernel object types (both named and unnamed), so the number of other types of objects (threads, events, ...).

Richard you are wrong here.See… – techno Dec 22 '15 at 4:08

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
Richard, thanks for the comment, didn't know about local access. – Hikedaya Mar 20 '11 at 11:44
