System.getProperty("user.name") returns HOSTNAME instead of currently logged username

Here 

System.getProperty("user.name");

returns host-name of windows server 2008 machine instead of currently logged in user name.

Below is my code 

final String user = System.getProperty("user.name");
logger.info("User Name : " + user);

I want to know how System.getProperty works in java and on windows server 2008? and why is it returning wrong value in this case?

to display list of all properties that are set in java, try the below code

   public static void main(String[] args)
   {
        Properties prop = System.getProperties();
        Set<String> a = prop.stringPropertyNames();
        Iterator<String> keys = a.iterator();
        while (keys.hasNext())
        {
            String key = keys.next();
            String value = System.getProperty(key);
            System.out.println(key + "=" + value);
        }
   }

Just checked this: System.getProperty("user.name"); returns the value from environment variable USERNAME, so check what set USERNAME says in CMD window
