Hi,

I have an active directory in my server(Window server 2003) with domain name "mycompany.com". I have another system which is in LAN with the Server, in which I am developing a web application(using C#). I have to fill up a drop-down in my application with the domain list that is present on the server. I am new for working on server OS, and LDAP and Active Directory. Can anyone please help me how I can do this?

Thanks in advance.

Solution 1

Assuming your server is already in the domain, you can use:

C#

List<string> controllers = new List<string>();
Domain domain = Domain.GetCurrentDomain();
foreach (DomainController dc in domain.DomainControllers)
{
  controllers.Add(dc.Name);
}

Thanks for the help. But, I am not executing the application on server. I am executing it in another system. How can I connect to server from my system to get the domain names?

Is that other server running in the same domain? If so, the logic still applies.

No, it is not in the same domain. When use your piece of code I am getting an exception saying "Current security context is not associated with an Active Directory domain or forest."

For this, I guess I have to first connect to the server using "LDAP://" kind of a url. But, I am not sure how to connect to the server. Can you please help me?

Part of the problem you are having here is that your IIS account will probably not be running as a domain account. Have a look at this thread for more information of things to do: http://directoryprogramming.net/forums/thread/1103.aspx
