/*
NETUSER.C -- a sample program demonstrating NetUser API functions.
This program requires that you have admin or accounts operator
privilege on the specified server.
usage: netuser [-s \\server] [-u username] [-p password]
[-c comment] [-v privilege level]
where \\server = Name of the server. A servername must be preceded
by two backslashes (\\).
username = Name of the user.
password = Password for the user.
comment = Comment string for the user.
privilege level = Privilege level for the user
(0=Guest, 1=User, 2=Admin).
API Used to...
================== ============================================
NetUserAdd Add a new user with a level 1 call
NetUserEnum List of users and user comments
NetUserGetInfo Display user details
NetUserSetInfo Disable, then re-enable the account
NetUserPasswordSet Change the new user's password
NetUserSetGroups Set the groups to which a user belongs
NetUserGetGroups Get the groups to which a user belongs
NetUserDel Delete the new user
NetUserModalsGet Get current modals for users in database
NetUserModalsSet Increment the password history length by one
This code sample is provided for demonstration purposes only.
Microsoft makes no warranty, either express or implied,
as to its usability in any given situation.
