How to programatically find out (enumerate) all existing Windows User-Groups ??

[Honza]

Hi to all

What I need is to enumerate all existing windows user-groups (those like Administrators, Power-Users etc. but even my own created groups, I think you know what I mean) - all within some C# code.

I thought this might be easy but I searched all the Internet to find the solution, however, I still can't do it...

Is there anybody who could help me ???
Thanks a lot, I really really need your help.

If you are talking about the AD groups (or domain groups):

using System;
using System.DirectoryServices;

class Class1
{
[STAThread]
static void Main(string[] args)
{
DirectoryEntry entry = new DirectoryEntry("LDAP://YourDomainName");
DirectorySearcher searcher = new DirectorySearcher(entry);

searcher.Filter = "(objectClass=group)";

foreach (SearchResult res in searcher.FindAll())
{
Console.WriteLin(res.GetDirectoryEntry().Name.ToString());
}
}
}

Very cool ..
I do have a question that kind of goes with this.
Is there a way to findout what users belong to each group?

So I could generate a listing
GROUP:
GroupName
USERS IN GROUP:
User1
User2
...... ect

Thanks
