Hi, welcome back,

We may want to get the list of Active Directory Providers ("LDAP:", "WinNT:", "IIS:"...) with .NET the same way we do it with this VBScript:

Set ads = GetObject("ADs:")

For Each provider In ads

    Wscript.Echo provider.Name

Next

The information we need is here in the registry: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\ADs\Providers. So the following sample code will get the info we need:

using Microsoft.Win32;

...
    // Get the HKLM registry key

    RegistryKey RegKey = Registry.LocalMachine;
    // Open the sub-key which contains all the providers

    RegistryKey ProviderKey = RegKey.OpenSubKey(@"Software\Microsoft\ADs\Providers");
    // Get the list of the sub-keys

    string[] SubKeys = ProviderKey.GetSubKeyNames();
    // Create the string array which will hold the provider list

    string[] ListOfProviders = new string[SubKeys.Length];
    // Now add all providers to the array

    for (int Count = 0; Count < SubKeys.Length; Count++)

    {

        ListOfProviders[Count] = SubKeys[Count] + ":";

    }
    // Show the list of providers

    foreach (string providerName in ListOfProviders)

    {

        MessageBox.Show(providerName);

    }

...

I hope this helps.

Cheers,
