- TITLE :Share and User Limits
- PRODUCT :Microsoft Windows NT Advanced Server

- --------------------------------------------------------------------------
- The information in this article applies to:
-
- - Microsoft Windows NT operating system version 3.1
- - Microsoft Windows NT Advanced Server version 3.1
- --------------------------------------------------------------------------
-
- Microsoft Windows NT and Windows NT Advanced Server do not impose any
- limitations on the number of shares they can have. They also do not have
- set limits on the number of users who can access the server.
-
- Although there is a limit of 254 NetBIOS sessions for each process within
- Windows NT, it does not apply to the default workstation or server
- components. The workstation and server services writes to TDI directly
- instead of calling for NetBIOS services. The TDI is a 32-bit interface and
- hence such a limit is no longer applicable.
-
- In addition, NBF (NetBIOS Frame) has a unique way of creating virtually an
- unlimited number of connections. A TDI handle is associated with each Local
- Session Number (LSN) and the corresponding Network Address. The TDI handle
- is then related to the process that established the connection. The
- translation of a process ID and LSN into a TDI handle is done by
- NETBIOS.SYS.
-
- For each binding path (LANA number) there can be 254 sessions per process.
- Windows NT provides separate address space for each process. The number of
- processes is thus limited by the available memory. In other words, the
- limitation on the number of shares or users depends on the available
- resources. By themselves, Windows NT and Windows NT Advanced Server do not
- impose any of these limitations. The total amount of memory available for
- all processes in a 32-bit scheme is 2 gigabytes (GB) ( 2 GB for system and
- 2 GB for programs) which can provide the address space for a very large
- number of processes.

- For more information please refer to pages 13 and 632-637 of the Microsoft
- Windows NT Resource Guide, Volume 1.
