Get PC Names on the Network

[sanders720]

I am trying to get a listin of all the PC names on the network and add them to a listbox. The code builds fine, but it does not work.

The error I get is:

An unhandled exception of type 'System.Runtime.InteropServices.COMException' occurred in system.directoryservices.dll

Additional information: The server is not operational

I am running Windows XP. Any help would be greatly appreciated!


private void Form1_Load(object sender, System.EventArgs e)
{
DirectoryEntry entry = new DirectoryEntry("LDAP://microsoft");
DirectorySearcher mySearcher = new DirectorySearcher(entry);
mySearcher.Filter = ("(objectClass=computer)");

foreach (SearchResult d in mySearcher.FindAll())
{
this.lstPCNames.Items.Add(d.GetDirectoryEntry().Name.ToString());
}
}

Is there any hope for some guidance on this one?
