Here is my code:

///////////////////////////////////////////////////////////////////////////

SQLDMO._Application SqlServer = new ApplicationClass();
try
{

SQLDMO.NameList servers = SqlServer.ListAvailableSQLServers();

for(int i=0;i<servers.Count;i++)
MessageBox.Show(servers.Item(i));

}
catch(Exception e)
{
MessageBox.Show(e.ToString());
}

///////////////////////////////////////////////////////////////////////////

The compiler tell me : Queryinterface is failed of the SQLDMO.NameList

What shall I do ?

Now the question is ListAvailableSqlServers make for the error!
Even if I tried your code
{
SQLDMO.Application App= new ApplicationClass();
SQLDMO.NameList servers = App.ListAvailableSQLServers();
}
The same error appeared!!!

God help me!

Well, Are you using VS .NET 2002 or 2003? And SQL Server 2000 with any SP? I
know a bug in VS .NET 2002 COM interops if you don't have SP3 in your SQL
Server...

Try with this code:

using System;
using System.Reflection;

internal class RetrieveSqlServerListApp {

public static void Main() {
// Invoke the ListAvailableSQLServers() method for a
SQLDMO.Application instance
Type oSqlDmoAppType = Type.GetTypeFromProgID("SQLDMO.Application");
object oSqlDmoApp = Activator.CreateInstance(oSqlDmoAppType);

object oSqlDmoListNames oSqlDmoAppType.InvokeMember("ListAvailableSQLServers",
BindingFlags.InvokeMethod,
null, oSqlDmoApp, new object[] {});

// Retrieve the number of available servers
Type oSqlDmoListNamesType = oSqlDmoListNames.GetType();

int nNumElementos = (int)
oSqlDmoListNamesType.InvokeMember("Count",
BindingFlags.GetProperty,
null, oSqlDmoListNames, new object[] {});

// Retrieve each SQL Server name
for (int i = 1; i <= nNumElementos; i++) {
object oSqlServer = oSqlDmoListNamesType.InvokeMember("Item",
BindingFlags.InvokeMethod,
null, oSqlDmoListNames, new object[] {i});

Console.WriteLine(oSqlServer.ToString());
}
}

}
