The NET Command is used to manage File Shares, Printer Shares and sessions as follows:

Display a local share
NET SHARE sharename

Display a list of computers in the current domain.
NET VIEW

To see a list of shares on a remote computer
NET VIEW \\ComputerName

To see a list of all shares in the domain:
NET VIEW /DOMAIN

To see a list of shares on a different domain
NET VIEW /DOMAIN:domainname

To see a list of shares on a remote Netware computer
NET VIEW /NETWORK:NW [\\ComputerName]

Create a new local file share
NET SHARE sharename=drive:path /REMARK:"text" [/CACHE:Manual | Automatic | No ]

Limit the number of users who can connect to a share
NET SHARE sharename /USERS:number /REMARK:"text"

Remove any limit on the number of users who can connect to a share
NET SHARE sharename /UNLIMITED /REMARK:"text"

Delete a share
NET SHARE {sharename | devicename | drive:path} /DELETE

Delete all shares that apply to a given device
NET SHARE devicename /DELETE
In this case the devicename can be a printer (Lpt1) or a pathname (C:\Docs\)

Join a file share (Drive MAP)
NET USE

NET FILE

Close a shared file (disconnect other users and remove file locks)
NET FILE id /CLOSE

NET SESSION /DELETE /y

NET SESSION \\ComputerName /DELETE

Notes:
NET SESSION displays incoming connections only, in other words it must be run on the machine that is acting as the server.

To create file shares the SERVER service must be running, which in turn requires 'File and Print Sharing' to be installed.
