Simple DistinguishedName question.

[therealbrandon]

I need the DistinguishedName of a user account on a Windows XP system. The computer does not belong to a domain, but a workgroup, instead. What would be the DN if the following were true?:

user name: brandon
workgroup: WORKGROUP
computer name: brandoncomp

Would it be?: CN=brandon, OU=USERS, DC=brandoncomp

And (I know this doesn't really pertain to this particular forum, but) how would I set that up in C# .NET, set set a string = "CN=brandon, OU=USERS, DC=brandoncomp"?

DistinguishedName is a directory property, not an nt username property. You cannot query for a DistinguishedName on a non-domain account.

Thank you for the answer... I forgot that I posted this already. What I was looking for was this (in case this helps someone) This is C# .NET, btw:

"WinNT://" + Environment.MachineName + "/userName"

pretty simplistic.



But, I would like to know one other thing. How can I tell if the user account exists? Right now I can see if the .Name == userName, but that doesn't seem like a good method, plus, if you try to call .Name and the user didn't exist, a COMException is thrown.

here's my code:

DirectoryEntry user = new DirectoryEntry("WinNT://" + Environment.MachineName + "/" + args[0]);

if (user.Name != args[0])
    // Error handling code here.

You'll have to use WMI.

To get you started: Here is a function that will get a list of all the users. All you have to do is compare the list to the username in question, and then you'll know if it exists.

public static void GetUsers()   
{

    SelectQuery sQuery = new SelectQuery("Win32_UserAccount", "Domain='ComputerNameHere'");   
  
     try   
     {   
            ManagementObjectSearcher mSearcher = new ManagementObjectSearcher(sQuery);   
  
            Console.WriteLine("User Accounts\n");   
  
            foreach (ManagementObject mObject in mSearcher.Get())   
            {   
                Console.WriteLine(mObject["Name"]);   
//Check if user name matches here!
            }   
      }   
      catch (Exception ex)   
      {   
            Console.WriteLine(ex.ToString());   
      }   
  
     Console.ReadKey();   
 }

Thank you very much. =)

Minor question: The line

Console.WriteLine(mObject["Name"]);

writes just fine to the console, but when I try:

if (mObject["Name"].ToString() == userName)

it needs the .ToString() so the types are identical... Why can it write to the console with or without the .ToString()?

[Craig Gemmill]

ToString() is called by the .NET Framework implicitly when printing any object as a string, since every .NET Object supports the ToString() method.
