很不幸,你可能要修改注册表
When you connect to a Web site that takes more than five minutes to return information to Internet Explorer, you may receive one of the following error messages:
Microsoft Internet Explorer error 10060 connection timed out.
Internet Explorer cannot open the Internet site <Web address>. The operation timed out.
原文请参照微软MSDN中的Q181050
1. IE要4.01 sp1以上版本.
2. 在注册表中HKEY_CURRENT_USER\Software\Microsoft\
Windows\CurrentVersion\Internet Settings中
加一DWORD类型ReceiveTimeout,值设大一些,单位是毫秒
3. restart computer.
