Thanks for the reply.
To bmartino1,
I run command "ipconfig /flushdns", it does not work., and i change the template with with UTF-8 to gb2312, all otheres are default. and There is a route for the client.
I mean it is loading the webpage slowly, same issue with opening lower level folders, and when it finished loading, when i click the link for upload and download the file, it is normal. and there is only 8 files under the two folders. I also think it is "cache/load" problem, Thanks.
To rejetto,
IE & Firefox on different computer, same problem
when i open the link on local computer, it is normal. no this issue, Thanks.
