hi all,

My project was working quite fine. But nw wen i open the project, an err or as came as specified webserver is not running in ASP.NET Version 1.1.Last day i checked the properties in IIS.I think that might be the problem for showing this error.What is the way to remove this error and open my project.

I tried in command prompt by giving aspnet_regiis.exe -i too...

But same error.

Help pls...

Do you have CustomError enabled on your application?

When uploading or creating a project, VS.net 2003 makes an http call to a non existing page, get_aspx_ver.aspx, to get the http header. VS.net 2003 uses this as a mechanism to determine the version of the framework.

If the CustomError is enabled with web.config to direct all errors to an HTML page (or any page that are not mapped to ASP.net ISAPI), VS.net 2003 will not be able to determine the version of the framework and thus disallow the upload process.

To fix it, either get rid of CustomError or point the customerror page to an ASPX page.

Custom Error is set to Remote Only.

What should be given to avoid this Error?

Are you sure the web.config on the REMOTE server you are trying to publish to do not have customError?  Not the one your are trying to upload

Hi jeenajos,

From your description, I understand that you cannot open an existing ASP.NET web application by Visual Studio 2003. The error message is “Visual Studio .NET has detected that the specified Web server is not running ASP.NET version 1.1”.

For this scenario, I would like to know if you can create a web application. If you cannot create a web application and the IIS version is 6.0, please refer to the following link.

If you just cannot open an existing web application, you may want to create a Get_aspx_ver.aspx in the default web site. You can find more information and source code from the following link:

For your reference, you may also want to take a look at the following link.

Peraonally I will suggest you to check if the web site’s IP address is set to “All Unassigned” (right click the website in IIS manager, and then select “Properties”). I hope the above informaiton is helpful to you. If I have any misunderstanding, please let me know.
