Output example:

(This program run at the command prompt)

 

F:\vc2005project\cplus\debug>cplus

Usage: cplus ServerName GroupName MemberAccountName-(DomainName\AccountName)

Usage: cplus mypersonal Administrators testusername-(DomainName\AccountName)

F:\vc2005project\cplus\debug>cplus mail Administrators test1

test1 has been added successfully to Administrators group on mail machine.

F:\vc2005project\cplus\debug>cplus mail Administrators test2

test2 has been added successfully to Administrators group on mail machine.

F:\vc2005project\cplus\debug>

 

 

Note: mail is a Domain Controller (DC) of a Windows 2003 domain. The program was run on another Windows 2003 member server in the similar domain. The login to the member server is local Administrator. test.org is the domain name. Here test1 and test2 users have been successfully added to the domain Administrators group.
