For some reasons, I don't use the standard port, I use the port 88. The solution is: Open table PortalAlias and add one row with HttpAllias is localhost:88, restart the iis, I restart window and It works.

Thanks for your solution.

Dotnetnuke is hard to config. Now, I have some other errors.

Hello, I now have a another problem. This is overriding the Module in DesktopModules of DNN.

I develop the Module as a website project, and when I build/rebuild the project, the files/folder of the project can not override to /DesktopModules/

I set all permission for Network Services user, current user, administrator user,IIS AppPool\myPool user. I run Visual Studio in ' run as Administrator' mode. but nothing happened.

I uncheck ReadOnly mode of folder DesktopModules/Module but it doesn't work, when I reopen the properties of folder is still 'Read only mode'

And this is my code in Build Events of the project.

xcopy "$(ProjectDir)*.ascx" "$(SolutionDir)\Website\DesktopModules\ChatModule" /E /I /Y /D
xcopy "$(ProjectDir)*.aspx" "$(SolutionDir)\Website\DesktopModules\ChatModule" /E /I /Y /D
xcopy "$(ProjectDir)App_LocalResources\*.resx" "$(SolutionDir)\Website\DesktopModules\ChatModule\App_LocalResources" /E /I /Y /D
xcopy "$(ProjectDir)Style\*.*" "$(SolutionDir)\Website\DesktopModules\ChatModule\Style" /E /I /Y /D
xcopy "$(ProjectDir)Images\*.*" "$(SolutionDir)\Website\DesktopModules\ChatModule\Images" /E /I /Y /D
xcopy "$(ProjectDir)Scripts\*.*" "$(SolutionDir)\Website\DesktopModules\ChatModule\Scripts" /E /I /Y /D
xcopy "$(ProjectDir)*.css" "$(SolutionDir)\Website\DesktopModules\ChatModule" /E /I /Y /D
xcopy "$(ProjectDir)Services\*.*" "$(SolutionDir)\Website\DesktopModules\ChatModule\Services" /E /I /Y /D


But when I change the folder in code to somewhere like xcopy "$(ProjectDir)*.ascx" "C\websites\buildhere" /E /I /Y /D => it works.

Please give me some suggests. oh, it made me crazy....

Thanks very very much!
