getting all users in a windows domain

[xxsodapopxx5]

Ok currently i am working in an environment with 20 computers all in the domain, which has about 40 users. These 40 users change often. I need to write an application that pulls all the usernames and if possible more information(i.e . There first and last name etc...) from the domain server. I am an administrator so i have full access to this server and can get to all the information manually through active directory on Windows Server 2003, but i found it redundant to have to type the information twice(i.e. once in active directory and again in the system i am tweaking). I have been researching the new classes for domains in the .net framework 2 and have come up blank any help would be great.

For this you have to query the active directory.

The Assembly is System.Director y Services.

Here Is for you,

//namespace required
using System.Director yServices;

//creating an instance of DirectoryEntry pointing to the //“TestOU” with valid credentials.
DirectoryEntry DE = new DirectoryEntry( @"LDAP://Norchio/OU=TestOU,DC=no rchio,DC=com"," Username","pass word",Authentic ationTypes.Serv erBind | AuthenticationT ypes.Secure);

// creating an instance of DirectorySearch er which will search in AD.
System.Director yServices.Direc torySearcher mySearcher = new System.Director yServices.Direc torySearcher(DE );

//setting up the search filters like if we want users from OU in AD
mySearcher.Filt er = ("(objectClass= user)");
Console.WriteLi ne("Users Listing from Active Directory");

foreach(System. DirectoryServic es.SearchResult resEnt in mySearcher.Find All())
{
ResultPropertyC ollection RCol = resEnt.Properti es;
foreach(string myKey in RCol.PropertyNa mes)
{
string tab = " ";
if (myKey == "samaccountname ")
{
Console.WriteLi ne(myKey + " ");
foreach(object myCollection in RCol[myKey])
{
Console.WriteLi ne(tab + myCollection);
}
}
}
}
Console.ReadLin e();

I am very greatful for your help, this is much appreciated... although there is something that i am not understanding. I Primarily program in vb.net 2005 so this code is somewhat foreign. I can interpret most of the code but can you explaing this line?

//creating an instance of DirectoryEntry pointing to the //“TestOU” with valid credentials.
DirectoryEntry DE = new DirectoryEntry(@"LDAP://Norchio/OU=TestOU,DC=norchio,DC=com","Username","password",AuthenticationTypes.ServerBind | AuthenticationTypes.Secure);

i do not understand what the first 3 parameters after the @

what path am i supposed to enter?
