Internet Explorer Cannot Display the Web Page

RobertoRegazzoni · August 24th, 2010, 12:22 PM

I'm not able to run any "Try It Out" in the book.
I always get âInternet Explorer cannot display the web pageâ.
My IE version is number 8.
My hosts file include the following entry:
127.0.0.1 localhost

Can I get a little help ?
Thanks
Roberto

Hi there,

What happens when you create a brand new web site in VWD, and then hit Ctrl+F5? Do you see anything?

Do you have anti-virus or security software running on your machine that may block the web server?

Hi Imar,

when I create a brand new web site in VS2008 (not VWD), and then hit Ctrl+F5, I get a page in the brower which says "Internet Explorer cannot display the web page".
The address displayed at the top of the page is something like http://localhost:3231/Chapter1/Default.aspx

In the page, there is a button to run a diagnostic program about connection problems, but the outcome does not give any hints:

ConnettivitÃ HTTP, HTTPS, FTP

infoHTTP: connessione a www.microsoft.com completata.
infoFTP (passiva): connessione a ftp.microsoft.com completata.
infoHTTPS: connessione a www.microsoft.com completata.

As for your question about anti-virus, the answer is yes: ESET NOD32.

Finally, the web server.
I'm a beginner in ASP.NET, but I suppose I'm using the embedded web server (not IIS).

Thank for any further tip.
Roberto

In that case, try disabling your anti-virus software. Does it work then?

If brand new sites don't work either, this must be a problem with VWD and the built-in web server on one hand, and your OS + installled software on the other hand. The trick is to find out what's causing it.... ;-)

Cheers

Imar,

I uninstalled and reinstalled from scratch VS2008,
I made a tour in the Windows update page,
I disabled the anti-virus and the firewall,
I downloaded Firefox and set it as the default browser without any import from my Internet Explorer settings,

but in the end nothing changed

Unable to connect
Firefox can't establish a connection to the server at localhost:1643.
* The site could be temporarily unavailable or too busy. Try again in a few moments.

* If you are unable to load any pages, check your computer's network connection.

* If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the Web.

What else can I try ?
Thanks

Someone recently had the same issue, and I believe it was related to IP V6 versus IP V4.
The topic can be found here: First project While you say your host file is already OK, it may put you in the right direction.

Otherwise, you may need to contact Microsoft for support, as something is wrong with Windows and / or VWD (my guess is that it's a Windows / networking / security software issue, and not a problem of VWD).

I would like to help you where I can, but issues like these are extremely difficult to fix remotely.

Cheers,

Imar

OK

I found the solution here http://forums.asp.net/t/1235447.aspx

The problem was to configure the ESET NOD 32 anti-virus to not filter devenv.exe (Visual Studio).

Thanks to everyone.
