How to retrieve the group SID from GroupName by C++

I have knew the administrator Group sid(Well-know-sid) is "S-1-5-32-544", but I research the msdn, I don't find any way can retrieve the Group sid by groupName.

I use ::NetLocalGroupEnum to list all groupName. Moreover, I want to know which group is administrator Group. Administrator Group's name is "administrator" by default. If someone modifies Administrator Group's name(ex: from "administrator" to "123" ), how can I know the "123" is belong to administrator Group. Now I use String to determine which group is Administrator Group, but if Group Name is modified, this way is not work. I also use ::NetLocalGroupGetInfo, but it's output structure only include name and comment but not group SID. Is any API or way is about input is the groupName, and OutPut is Group sid? Thanks!

Call LookupAccountSid() on your "S-1-5-32-544" SID. You'll get back a name with type SidTypeGroup.

As you correctly noted, the SID values are well-known (stable), so you use those as input. Account names can be localized, so those are the output.

I worked with PowerShell and found following information I hope this helps:

  1. Adding ActiveDirectory Module to PS
  2. run Get-ADGroup -Identity Administrators that Administrators is the name of your group enter image description here
