The NET SHARE command in Windows Server 2003 adds the grant of share permissions.

Prior to Windows Server 2003, when you opened a CMD.EXE window and typed net share /?, you would receive:

NET SHAREsharename          sharename=drive:path [/USERS:number | /UNLIMITED]                               [/REMARK:"text"]                               [/CACHE:Manual | Documents| Programs | None ]          sharename [/USERS:number | /UNLIMITED]                    [/REMARK:"text"]                    [/CACHE:Manual | Documents | Programs | None]          {sharename | devicename | drive:path} /DELETE

When I typed net share /? in a CMD.EXE window on my Windows Server 2003, I received:

NET SHARE sharename          sharename=drive:path [/GRANT:user,[READ | CHANGE | FULL]]                               [/USERS:number | /UNLIMITED]                               [/REMARK:"text"]                               [/CACHE:Manual | Documents| Programs | None ]          sharename [/USERS:number | /UNLIMITED]                    [/REMARK:"text"]                    [/CACHE:Manual | Documents | Programs | None]          {sharename | devicename | drive:path} /DELETE

allowing you to assign permissions to multiple user and groups without reverting to other tools, like RMTShare.exe or SubInACL.exe.
