Hi All

I have an ASP.NET project which was working fine until my PC went bang...
I have reinstalled Win 10 and reloaded all of my projects but one of them no longer runs. I did not write this project but do I need to maintain it so running it from within VS2015 is a must.
The project has no error or warnings but when I run it I get an error saying there was a temporary DNS error followed by Error code: INET_E_RESOURCE_NOT_FOUND. Not sure how to add a pic but can provide one if it would help.
Have tried in IE, Edge, Chrome and Firefox, all fail with similar error messages.

I have tried to step through the code but no failures and the first pages page pre-render executes OK.

My guess is that it is trying to get a resource from somewhere but I cannot for the life of me see what it is trying to load from where.

Has anyone else seen this error or have any idea if I can set a trace or something to see what it is trying to load?

Wasted 2 days in this so far... extensive Googling has not helped.

Thanks in advance for any advice anyone can offer.

What I have tried:

Googled everything but none of the proposed solutions have fixed the problem.

To see traffic (or its attempts) of what your computer is requesting you could utilize something like Fiddler if its an HTTP request. You could also utilize the netstat command.

And then one other question, are you on the same PC that is getting the resource not found error?

Thanks David,
Could not get fiddler to work at all but I am not familiar with the product and the documentation is not that clear on how to invoke it from VS.

Will look into netstat next.

As for you last question, yes, I am trying to run the project from within visual studio so it will be running under localhost.

Thanks

OK, not sure what the problem was so sorry if this came up when you were googling the error message, I cannot help you...

I eventually deleted the project and restored it from a backup (which is the same as I had done before!) and it runs just fine now.

The only thing I did differently was to run the project from Visual Studio 2012 instead of 2015...!
