My development machine (Vista) was working perfectly fine for over a year and then suddenly (without explicitly installing anything) I am unable to run the websites using ASP.NET development server.
The development web server starts fine, but IE cannot display the page:
Internet Explorer cannot display the webpage Firefox says - Failed to Connect, The connection was refused when attempting to contact localhost:49447.
Here is what I have tried so far:
* Disabling firewall
* Stopping anti-virus
* Stopping Windows Defender
It worked when I stopped all services using MSConfig and tried again. However, that disables most of the services, so is not a feasible long term solution.
After stopping all services, I tried starting services one by one to find out which one is causing problem.
These are the steps and results:
1. I found DNS Client Service was causing problem.
2. So I started all others and stopped DNS Client service, but then Network Location Awareness service started causing problem
3. I stopped DNS Client Service and Network Location Awareness and started all others, btu again something else is causing problem.
Clearly there is something common and fundamental at the root of this.
I do not know much about networking. Can someone guide me in right direction?

I was able to fix this on my computer by doing the following:
My host file contained this line for the localhost entry, which is how the host file ships with Vista, and i've never modified this line
::1 localhost
Replaced "::1 localhost" with the this:
127.0.0.1 localhost
"::1 localhost" has worked fine for me for well over a year, until this morning. Windows defender installed two updates, one yesterday and one this morning, my guess is that something in one of these updates caused this entry to not work anymore.

I have been having the same problem, as with your machine mine was running fine up until thismorning and now i cant run any websites in the asp development server. I havent found a fix yet hower i did notice that a windows update was installed just before the issue started so maybe this could be related.
