Hello, I have tried running my web-application project after I installed Windows Vista with new IE 7. Normally, I open the solution in VS, start debugging / running, ASP.NET devel. server launches, Internet Explorer launches and displays my page. The problem is that after starting running or debugging of the project, ASP.net dev.server starts, IE starts, BUT shows me standard page-not-found page (Internet explorer cannot display the webpage...). After that I connected to the server from other browser, which showed me asp.net generated error page. I have turned off "Show friendly HTTP error messages" option in IE, and nothing had changed. When I load a page without errors, it runs OK. But, I need to use IE in development cycle, I need to see the ASP.NET errors in the internet explorer, and not just the "Internet explorer cannot display the webpage". Until I solve this, I need to stick with different browser for a while. Do you know what should I do? I appreciate any help, thanks, Juraj

 OK, i got it resolved.

 You need to disable IPv6 for this to work,

the process is described for example here: http://rbazinet.wordpress.com/2007/10/25/aspnet-development-server-problems-under-vista/

 After I disabled IPv6 and restarted my computer, Internet Explorer normally displayed pages from ASP.NET development server.

 

 Thanks jborza!

 This happens for me both in Vista and Windows XP Tablet Edition ... and the solution of disabling IPv6 in the registry solves the problem ...

I have also found the following solution:

 If Vista gives you problems in saving the new file in the directory (it did to me) you can save into another folder (documents) and then move it. You will require administrative permissions to move it, but it works like a charm.

 Best!!!!

Thanks a lot for sharing the info.
