   Module Name:

       acctname.c

   Abstract:

       This module illustrates how to obtain user and group names
       Associated with accounts that have been renamed or localized. This
       sample works by building a Sid value and then looking up the name
       associated with that Sid value.

       For example, in a default English install of Windows NT, the local
       administrators group is called "Administrators." In a default German
       install of Windows NT, the local administrators group is called
       "Administratoren." This can lead to problems when managing users
       and groups if the proper steps are not taken.

       The following relative ID values are an index into an account
       database that represents a specific user or group. In DOMAIN_USER_
       and DOMAIN_GROUP_ cases, the relative ID is appended to the account
       domain Sid from the machine of interest. In the DOMAIN_ALIAS_ case,
       the relative ID is appended to a well-known Sid representing the
       BUILTIN domain that is consistent across machines.

       // Well-known users and groups...

       #define DOMAIN_USER_RID_ADMIN          (0x000001F4L)
       #define DOMAIN_USER_RID_GUEST          (0x000001F5L)

       #define DOMAIN_GROUP_RID_ADMINS        (0x00000200L)
       #define DOMAIN_GROUP_RID_USERS         (0x00000201L)
       #define DOMAIN_GROUP_RID_GUESTS        (0x00000202L)

       // well-known aliases ...

       #define DOMAIN_ALIAS_RID_ADMINS        (0x00000220L)
       #define DOMAIN_ALIAS_RID_USERS         (0x00000221L)

       for visualizing Sid values:

       If no Command line arguments are specified, names are looked up
       on the local machine. If argv[1] is present, the lookup occurs
       on the specified machine.

       For example, acctname.exe \\winbase will look up names from the
       machine named \\winbase. If \\winbase is a default German install
       of Windows NT, names will appear in German locale.
