WinXP/2000/2003下关闭这些网络端口：
第一步，点击“开始”菜单/设置/控制面板/管理工具，双击打开“本地安全策略”，选中“IP安全策略，在本地计算机”，(或者运行gpedit.msc)在右边窗格的空白位置右击鼠标，弹出快捷菜单，选择“创建IP安全策略”。

为新的安全策略命名为关闭指定端口策略；再按“下一步”。

则显示“安全通信请求”画面，在画面上把“激活默认响应规则”左边的钩去掉
http://img.pconline.com.cn/images/bbs4/20081/9/1199854864902.jpg (http://softbbs.pconline.com.cn/viewpic.jsp?imgUrl=http%3A%2F%2Fimg.pconline.com.cn%2Fimages%2Fbbs4%2F20081%2F9%2F1199854864902.jpg)
点击“完成”按钮就创建了一个新的IP安全策略。

在“属性”对话框中，把“使用添加向导”左边的钩去掉，然后单击“添加”按钮添加新的规则。随后弹出“新规则属性”对话框。在画面上点击“添加”按钮
http://img.pconline.com.cn/images/bbs4/20081/9/1199854891735.jpg (http://softbbs.pconline.com.cn/viewpic.jsp?imgUrl=http%3A%2F%2Fimg.pconline.com.cn%2Fimages%2Fbbs4%2F20081%2F9%2F1199854891735.jpg)
弹出IP筛选器列表窗口；把“使用添加向导”左边的钩去掉, 再点添加

进入“筛选器属性”对话框，首先看到的是寻址，源地址选“任何IP地址”，目标地址选“我的IP地址”
http://img.pconline.com.cn/images/bbs4/20081/9/1199854910143.jpg (http://softbbs.pconline.com.cn/viewpic.jsp?imgUrl=http%3A%2F%2Fimg.pconline.com.cn%2Fimages%2Fbbs4%2F20081%2F9%2F1199854910143.jpg)
点击“协议”选项卡，在“选择协议类型”的下拉列表中选择“TCP”，然后在“到此端口”下的文本框中输入“445”，点击“确定”按钮，这样就添加了一个屏蔽TCP445（RPC）端口的筛选器，它可以防止外界通过445端口连上你的电脑。
http://img.pconline.com.cn/images/bbs4/20081/9/1199854922038.jpg (http://softbbs.pconline.com.cn/viewpic.jsp?imgUrl=http%3A%2F%2Fimg.pconline.com.cn%2Fimages%2Fbbs4%2F20081%2F9%2F1199854922038.jpg)
点击“确定”后回到筛选器列表的对话框，可以看到已经添加了一条策略，重复以上步骤继续添加TCP137、139、445、593端口和UDP135、139、445端口，为它们建立相应的筛选器。

重复以上步骤添加TCP1025、2745、3127、6129、3389端口的屏蔽策略，建立好上述端口的筛选器，最后点击“确定”按钮。
返回到“新规则属性”对话框中，选择“关闭端口的筛选列表”，然后点击其左边的圆圈上加一个点，表示已经激活。
