Platform SDK: Network Management

NetGroupAddUser

The NetGroupAddUser function gives an existing user account membership in an existing global group in the security database.

Security Requirements

Windows NT: Only members of the Administrators or Account Operators local group can successfully execute the NetGroupAddUser function.

Windows 2000: If you call this function on a Windows 2000 domain controller that is running Active Directory, access is allowed or denied based on the access-control list (ACL) for the securable object. The default ACL permits only Administrators and account operators to call this function. On a member server or workstaion only Administrators and account operators can call this function. For more information, see Security Requirements for the Network Management Functions.

Remarks

If you are programming for Active Directory, you may be able to call certain Active Directory Service Interface (ADSI) methods to achieve the same functionality you can achieve by calling the network management group functions. For more information, see IADsGroup.
