server is not running asp.net version 1.1

When you try to create a new ASP.NET 1.1 project or try to open, you may receive the following error message

visual studio has detected that the specified web server is not running asp.net version 1.1

If you have already googled and come across Microsoft knowledge base article 817267.
PRB: "The Specified Web Server Is Not Running ASP.NET Version 1.1" Error Message When You Create ASP.NET 1.1 Application ( MKB817267 )

don't get confused by this article, the article applies to windows 2003 server.

You can actually fix this problem in less than 5 minutes and in 3 steps:

1) Open Add/Remove program and uninstall dot net version 1.0.

2) If dot net version 1.0 is not in the list of installed programs, find the following folder and delete it if found C:\WINDOWS\Microsoft.NET\Framework\v1.0.3705

3) run the executable with the following option from command window: C:\WINDOWS\Microsoft.NET\Framework\v1.1.xxxx\aspnet_regiis.exe -i

And you should be back in business.

Thanks a lot, but it works only for opening a new project. Once I wanted to debugg my project I got another error saying: "Unable to start debugging on the web server. The project is not configured to be debugged"
Can you please help me with that.
Thank you in advance.

Hi Anil,

I did aspnet_regiis -i and now it is able to connect to web server. but the problem is it is unable to even run simple "hello world" Web Service. It gives me error and i.e. "file or assembly name cmb0wyy-.dll(the name of dll changes every time i try to run it) or one of its dependencies was not found".

Any help is greatly appreciated.

Thanks.

I had the same problem, but I figured out that the machine.config file was having
. I modified the attribute enableVersionHeader to "true" (this is default setting). and when I opened the project. It worked like a charm.
