How can I query teminal services activity remotely?

Question

I want to query our servers to see look for disconnected/idle sessions. I know I can use 'query.exe', but I'd prefer something that's easier to work with from code.

WMI would be my preference.

Thanks.

If you are using a .NET language, you might try Cassia. In C#, the code would be:

using System;
using Cassia;

namespace CassiaSample
{
    public static class Program
    {
        public static void Main(string[] args)
        {
            ITerminalServicesManager manager = new TerminalServicesManager();
            using (ITerminalServer server = manager.GetRemoteServer("server-name"))
            {
                server.Open();
                foreach (ITerminalServicesSession session in server.GetSessions())
                {
                    if ((session.ConnectionState == ConnectionState.Disconnected)
                        ||
                        (session.ConnectionState == ConnectionState.Active)
                        && (session.IdleTime > TimeSpan.FromMinutes(1)))
                    {
                        Console.WriteLine("Session {0} (User {1})", session.SessionId, session.UserName);
                    }
                }
            }
        }
    }
}

EDIT: Updated sample code for Cassia 2.0.
