请问:一个Winfrom怎么防止远程登录开

请教:一个Winfrom如何防止远程登录开多个程序?
服务器是win2003,程序是放在“启动”那里自动启动的,但多个用户远程登录后会造成程序开多个,有什么办法防止程序在windows系统中只开一个? (不做成“服务”的前提下),先谢谢了!!!

C# code
不同用户没试过试过,我有当前用户不能多开的 你试试不同用户行不行。        #region 程序只运行一次        /// <summary>        /// 程序只运行一次        /// </summary>        /// <returns>null</returns>        public static Process RunningInstance()        {            Process current = Process.GetCurrentProcess();            Process[] processes = Process.GetProcessesByName(current.ProcessName);            //Loop through the running processes in with the same name             foreach (Process process in processes)            {                //Ignore the current process                 if (process.Id != current.Id)                {                    //Make sure that the process is running from the exe file.                     if (Assembly.GetExecutingAssembly().Location.Replace("/", "\\") == current.MainModule.FileName)                    {                        //Return the other process instance.                         return process;                    }                }            }            //No other instance was found, return null.             return null;        }         #endregion
