When I try to run a ASP.NET web form then the ASP.NET development server is opening but no browser is opening. After some time a message box in that an error is popping up. The error is: ' Unable to connect to ASP.NET development server '. Please help me, what I should do to solve the problem.

Hi there,

Do you have anti-virus or security software running that prevents the web server from starting up correctly?

Yes I have anti vir anti virus installed in my pc. Also I have comodo fire wall installed in my system. Do I need to uninstall the anti virus and firewall ?

Hi there,

No, you probably don't need to uninstall it, but you need to change its configuration to allow the web server to start up and run.

Cheers,

Imar
