Answer 1

This solution didn't work for me but this function worked great:

public static string GetUserFullName(string domain, string userName)
        {
            DirectoryEntry userEntry = new DirectoryEntry("WinNT://" + domain + "/" + userName + ",User");
            return (string)userEntry.Properties["fullname"].Value;
        }

You should call it that way:

GetUserFullName(Environment.UserDomainName, Environment.UserName);
