Python：python-ntlm（官网地址:http://code.google.com/p/python-ntlm/）是一个用来访问NTLM认证网址的module, 代码的那边搬过来的。我测试可用：

    url = "http://www.xxx.com/info.aspx"  #就是注意这个是获取信息的地址。不是登录的。刚开始测试用的登录的地址。那样是不行的。
    user = u'randy\\test'
    password = 'testpwd'
        
    passman = urllib2.HTTPPasswordMgrWithDefaultRealm()
    passman.add_password(None, url, user, password)
    # create the NTLM authentication handler
    auth_NTLM = HTTPNtlmAuthHandler(passman)
    
    # create and install the opener
    opener = urllib2.build_opener(auth_NTLM)
    urllib2.install_opener(opener)
    
    # retrieve the result
    response = urllib2.urlopen(url)
    print(response.info())
    print(os.path.join(os.getcwd(),"1.txt"))
    #outfile = open(os.path.join(os.getcwd(),"1.htm"), "w")
    #outfile.write(response.read())
