How to solve “Microsoft Visual Studio (VS)” error

Question

PROBLEM

If you start using "Microsoft Internet Information Services Express (IIS)" from "Microsoft Visual Studio (VS)" you may get when you run Build this error message

Unable to connect to the configured development Web server.

Failed to register URL "http://{ip_addr}:{port}/" for site "{project_name}" application "/". Error description: Access is denied. (0x80070005)

What kind of rights is it?

Answer 1

Opening Visual Studio as administrator will fix the problem.

Answer 2

I tried almost all the options above, none of them worked for my scenario. Finally I was forced to uninstall IIS Express, re-start the machine, and install the same version again from Microsoft.

Anyway thanks for all the suggestions above.

Answer 3

I've discovered the problem seemed to happen a lot on Intel PCs, so, after further investigation, I discovered that the Intel(R) Driver & Support Assistant (preloaded on many brands) was the culprit. It was using the same port # as one of my projects & randomly selects ports. The clincher was that it doesn't always hold the port open, only when checking for updates, but once it does, it stays locked until you reboot the machine. Solution: Disable this service (you really don't need it). Other services can do the same (Quickbooks Web Connector TINY.EXE, antivirus programs, or any utility that opens a port) and it may appear random.

SOLUTION

This means that you are missing the right for using it. Create it with Netsh Commands for Hypertext Transfer Protocol > add urlacl.

1) Open "Command Line Interface (CLI)" called "Command shell" with Win+R write "cmd"

2) Open CLI windows like administrator with mouse context menu on opened windows or icon "Run as administrator"

3) Insert command to register url

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

NOTE:

• For remove you can use: netsh http delete urlacl url=http://{ip_addr}:{port}/
• If not work restart Microsoft Windows (WIN) and then open project and build again.
• Sometimes these symptoms may be the same like "Unable to launch the IIS Express Web server”.

Answer 5

I solved this just now, in the system tray (bottom right) you can click ion the IIS icon and stop the current site, then it allowed me to run.

Answer 6

This happened to me on Windows 7 and VS 2013 while viewing a project on the browser after build. I only had to close the browser "Chrome" then made sure that the port is not in use in my Network Activities using some utility then tried again and worked without any problem.
