Error description:

I write a ASP.NET program, I use HttpContext.Current.User.Identity.Name to store users which visit our site.

I build a website using IIS7.0 and I can see this the website in my IE. However, the website cannot be viewed by other computers. Once I meet this problem, I think it's "FIREWALL" issue. However, I cannot close the firewall because my corportatoin not allow me to turn down firewall. So, I have to configure it:

The solution can be :

IIS7.0同局域网的计算机通过输入我的IP地址无法访问我的页面,但是在本机访问却没有问题，以前用IIS6.0的时候是可以的解决方案有两种。一种是关闭防火墙. 另一种开放特定端口：
开始---所有程序---管理工具---高级安全 Windows 防火墙, 在高级安全 Windows 防火墙的左边栏，选择“入站规则, 在右边栏选择"新建规则“。
在弹出的窗口依次选择：选中端口---下一步---选中TCP以及特定本地端口，填入要开放的端口号（这里填入指定端口号）---下一步---选中允许连接---下一步---选中所有选项---下一步---填入名称（随便一个标识）---完成

It's ok using this solution.
