ASP.NET Development Server Problems Under Vista

Found a more elegant solution for you (don’t kick yourself too hard).
Disable IPv6 in your network adapter’s properties (you likely wont need it for a couple of years yet, and M$FT should have figured it out by then).
This works for both IE and Firefox (without changing Firefox’s config).

@Charles I tried this and it did not work, I had to do what I documented in my post. I found out disabling IPv6 on the network adapter did not disable for loopback.
Thanks.

Hi
I have same problem too in vs2008 on vista .
I configured my firefox as you say , its working good
But my system , still not working by localhost .
if you find any solution , please tell to me by my email.

@Saeed This post IS a solution. If you follow it, it works on Vista.

wow … Thanks a lot Rob! This was happing to me also … I tried to disable IPv6 in network adapter’s properties as Charles suggested without success …
Thanks!

@Portella Great, glad I could help. It just shows Vista is in need of a service pack or two.

what about windows xp pro, i have wrong ports in IE and in ASP.NET development server when i load local webpage..
Visual studio 2008 pro..

@Marko Not sure about XP Pro, I have never see issues with VS 2008 and XP Pro.

Wow. Interesting.
I’d be curious to see what Vista’s hosts file looks like, though. There should be some IP attached to localhost in there.

i did not find the Disables Components in my Parameters. I’m still unable to solve my problem in IE, however, it’s working fine in FireFox now

HI!
I have Vista Home Premium too. I still could not make the VSW 2008 work. I have the same problem as Siddique. I don’t see any DisabledComponents in my Registry.
Do u know why?
Thanks

on my vista and vs2008 i only have to change in IE from http://localhost:portnum/SomePage.aspx to http://127.0.0.1:portnum/SomePage.aspx and everything works

I found even better way, just comment int system32/drivers/etc/ line containing “[:::1] localhost”

@Michal Great info, I will give it a try on my next Vista install.

thanx Rob Bazinet and michel,better method is comment int system32/drivers/etc/host line containing :::1 localhost

#14 is the best solution.
Comment out the line in the host file with where ::1 is mapped to localhost. Worked straight away.

Fantastic! It saved me a lot of work!
Thanks so much!

@Edson Great to hear. Helping out another person makes having a blog worth it.

Ad an extra : before the ‘::1′ in the line where ::1 is mapped to localhost. Worked straight away.
It Should be :::1 instead of ::1. A little ‘bug’ in Vista.

RE: ASP.NET Development Server Problems Under Vista

I have wanted to be a Windows Vista user and developer since before it was released, but there always seemed like something didn’t work or some application I used kept crashing. The pure pain of the performance of Vista alone was not worth the "upgrade"

I have Vista SP1
and VS2008
and it works…
and I’m testing
Vista (withou SP) with VS2005 and VS2008
and it works fine!
I think it’s depending on Hardware
because one of my friends has the same problem!

Thanks Richard vN.
I was one of the eager adopdters of Vista as I wanted to have some hands-on experience of dev’ing for the OS before it took root and I’ve had this problem for years.
The simplicity of your solution shows how little I know about IPv6 but like Rob, I was never comfortable with the wholesale disabling of it either.
The amazing thing is that my current installation of Vista was installed from a disc with SP1 slipstreamed in, suggesting that this ‘bug’ seems to have slipped by M$.

@D-Man I just installed an additional Vista system here with SP1 slipped as you did, I had the same problem again. I really like the solution of simply adding an additional ‘:’ in the hosts file, very elegant for sure.

thanks a lot you solved my problem

:::1 instead of ::1
works for me for internet explorer

Thank you so much! Worked for me, too. To make things perfectly clear, you want to go to C:WINDOWSsystem32driversetc and edit the "hosts" file with Notepad. In my case (running Windows XP Media Center Edition), I commented it out by using a pound sign.
I replaced
127.0.0.1 localhost
with
#127.0.0.1 localhost

I found another little work around that MUCH more usefull.
Download Fiddler and set it up as proxy.
Turn off that Firefox doesn’t use the proxy for localhost and 127.0.0.1 ofcourse. And if you have trouble reaching the server, setup a custom startpage that’s pointing to 127.0.0.1 instead of localhost.
This way you can monitor your traffic with the development server and it also gets rid of the problem that it’s slow.

for me, I found that the port that the ASP.net dev server was starting on was different to the one that the browser was trying to connect to.
make sure you check the settings of your dev server (right click the satellite icon -> properties) and check that the port # is the same as the one that gets appended to your url

RE: ASP.NET Development Server Problems Under Vista

Hola amigos, pues resulta que probando una aplicación Web en el Visual Studio 2008 no me cargaba, en

Andrew, for me this is the exact situation. And I guess there is a bug in VS 2008 because it is trying to start on one port and sees that it is unavailable and then start the instance of the webserver on another port.

Thank you so much guy! D

Thanks guy you really saved my life

You can disable IPV6 against localhost by editing the host file:
C:WindowsSystem32driversetchosts
::1 localhost
Add a # in front of this line to make it a comment. Restart your PC. Good to go.

Thank you so much guy!
localhost <> 127.0.0.1

:::1 instead of ::1
works for me and for internet explorer
Thanks a lot!

rob,
Thanks Very Much for solving my problem

I have the similar issue and after testing these solutions I still had the problem. When I configured IIS I had named the Binding for port 80 (default web site) with the fully qualified name for the machine (machine.company.com). I solved the issue by adding a second binding rule to port 80 with host name of localhost.

Excelente solución la de agregar : , agradezco mucho su ayuda!

Oh thaks guys, that change works for me
Saludos

Thanks for this … strange that this has not been corrected by MS

Tnx a lot… My problem solved by this issue

hi! that was very helpful. thanks

HIII thanks alot its really working……………………..

I never had this problem on VS2008 and Vista until I tried to use II7 instead of Visual studio web server and I followed instruction on VS2008 and enabled "IIS metabase and IIS 6 configuration compatibility" option under Windows Features and another option that I don’t remember now. The next day I started to have this problem. Of course I fixed it by disabling the line mentioned by michal, but I thought it’s worthwhile to mention what might be causing this issue.

Reading all of the comments is interesting. I just "upgraded" from XP Pro to Vista Home Premium and I like it. My problem with IIS 7 seems to be the opposite. I can grab my web services via "LocalHost:<port> but not via my external static IP. Any thoughts?

I hope this helps someone. I had to update my hosts file and in addition i had the web site http://localhost to my local intranet sites in internet options,security,advanced,

Hello, according to the changes that need to be done to the host file, I’ve tried it and when I want to save, it said that the file can’t be changed. Please help.

This helped me a lot in developing something for work. Had some issues with Vista.

This helped a ton in a problem I was having setting up the server.

Wow ! I reformatted my PC couple of times before it hit me that this may be a weird problem from Microsoft and started searching. Thanks a lot !

Thank you so much, I was stuch for a long time in this issue now I know the reason
I just change the IP from ::1 to 127.0.0.1 in the host file in etc folder, and now It works fine

Thank you. Great post in fact brilliant post because i could not get any help from microsoft

Thanks!!!
@fariz: run notepad as admin, and then open the hosts file from notepad.

Funny thing is though, that the new : makes Vista go completely bogus and ignore the entry.Putting a # in front of it would be better. Anyway, what does the ::1 stand for? It’s probably IPv6 something, but what does it mean? What does it actually do?

very useful post, This article helped a ton in a problem.
thanks a lot

hi,
i am using vs 2005, my site has a lot of pages and images on the page starts with the prefix "/" that indicate root. it work fine when i deploy site on production , but it did not work in asp.net development server.
locahost/…/pages.aspx image: "/images/logo.gif"
so when it detect "/" it search outside the mysite directory which is the main directory of my site. how can i point to mysite.

ASP.NET’s problem Development Server also can happen put a restriction of protocol in your antivirus, for ejemlo in NOD32 it is necessary to enable the filters of HTTP protocol and POP3 in order that it(he,she) could execute developmen server.

This is really off topic, but I thought I’d chime in. I have installed a single web site on my IIS 7 on Vista, and it only serves a phantom page (that reads "It Works!"). This text is nowhere in my web site, and worse yet, is nowhere on my computer (calling http://localhost). Furthermore, specifying the index page brings up HTTP Error 404. Searching my computer’s file contents for ‘It Works!" brings up no matches. So, I’m stymied. I do better with IIS 5 on XP. I can’t make Vista work with IIS at all I guess. Of course, that file HAS to be here somewhere, but I can’t locate it, or any directories that might be acting as the virtual web on my machine. Search is not working right or something. Odd. But I haven’t given up yet, even after 2 days of hacking this.
