Unable to launch IIS Express Web Server in VS 2013

Question

I have an application in MVC 4 using VS 2013.

This is very strange,everything was working fine till last night but today morning when I started working and tried to run my application I found the following error:

Unable to launch IIS express web server.
Failed to register URL"http://localhost:62707" for site...
Access denied(0x80070005)

I searched regarding this since morning and I got solutions for this which I tried as:

• I deleted IIS Express folder from my documents several times and tried running the application by reopening it but that dint work.

• I tried with changing the binding in applicationhost file from http to https. With this the only thing that got changed is the error is now showing:

  Unable to launch IIS Express Web server. The start URL specified is not valid.

• I restarted my system many times as per some of the suggestion . Also my browser too .

• I tried ending the process for IIS Express from Task Manager.

But nothing seems to be working for me and even after trying almost all of the possibilities for hours I kind of got stuck at this point.

Solution

You can try this:

• Open "Command Line Interface (CLI)" called "Command shell" with "Win+R" write "cmd" put this command for removing the urlacl.

  netsh http delete urlacl url=http://{ip_address}:{port}/
  

• Then add the url for everyone

  netsh http add urlacl url=http://{ip_address}:{port}/ user=everyone
  

• Then close the VS and delete the IISExpress folder from Documents path as:

  %userprofile%\Documents, e.g. C:\Users\[you]\Documents\IISExpress
  

• Re-run your application.

worked for me as well. Didn't happen until I used ccleaner and ccleaner's registry cleaner on my PC and restarted.

Thanks Vishal, this solved my problem. As a note, you can view all the reserved URLs with: netsh http show urlacl

In cmd I got error as: URL reservation delete failed, Error: 2 The system cannot find the file specified.
