下载安装Cntlm之后。仅仅须要改动cntlm.ini文件，提供身份认证必要的信息，然后以服务的方式启动cntlm就能够了。
在cntlm.ini中有例如以下几个重要的配置是可能须要改动的：
Username - your domain/proxy account name
Domain - the actual domain name
Workstation - NetBIOS name of your workstation; Cntlm tries to autodetect it, but you might want to set it explicitly should dialect detection fail (see below)
Proxy - IP address (or ping-able hostname) of your proxy; if you use several alternative proxies or know of backup ones, use this option multiple times; if one stops working, Cntlm will move on to the next
Listen - local port number which Cntlm should bind to; the default is OK, but remember you can't have more than one application per port; you can use netstat to list used up ports (lines with LISTEN)
