VS 2005/2008 and Vista – IE cannot display the webpage

Vista and Visual Studio - problems with IPv6 and internal WebDev.WebServerI recently reinstalled my laptop completely (it is very nice Dell XPS M1330) and took that opportunity to make it into decent development machine (w/o all the stupid preinstalled applications).

Installed also Visual Studio 2005 and 2008, SQL 2005 Express and all the little tools necessary (ClipX for example).

Fired up latest web site on which I work on, F5 and … nothing – dreadfull message of “Internet Explorer cannot display the webpage”.

Ok, no panic here, let try Visual Studio 2008 with same web site; nothing 🙁 Same site, on two other development machines (Vista & Vista 64) under VS 2005 and VS 2008 works w/o problem.

Started researching and debugging; it turns out that next generation protocol IPv6, or its implementation on Vista clashes with integrated web server WebDev.WebServer.exe; WebDev has a problem finding localhost address in default configuration.

Easy fix for this is to comment ::1 entry in hosts file:

Uncomment ::1 in hosts file to correct webdev / visual studio problems

No restart is needed, either of computer or Visual Studio.

(to edit hosts file you can use notepad started with elevated rigths or “Run as administrator“; in Open dialog you type in %windir%System32driversetchosts)

  3. As all previous poster. Thank you very,very much. After spending half a day trying to find out why my websites didn’t work using the build in webserver and even installing VS 2008 again, I finally found your site. Either this problem is very rare or nobody wants to write about it, even on the site of MS I couldn’t find anything. But this solved it for me. Thanks again.

  7. Hello,

    Unfortunatly, I have the same trouble, but not she same configuration.
    I’m running VS2005 on WXP (no IPv6)
    My host file does not have any “::1 localhost” entry
    The issue is comming randomly.

    Does someone have another solution?
