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

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

I solved the error by changing the port for the project.

I did the following steps:

1. Right click on the project.
2. Go to properties.
3. Go to Server tab.
4. On tab section, change the project URL for other port, like 8080 or 3000.

Good luck!

Solution 1

If you use a newer version of Visual Studio, you may not have this problem. I'm currently using Visual Studio 2015 and it works great.

Solution 2

You can solve this problem by changing the project's port number.
Because the reason is a port number conflict with some other application.

I had the same issue and fixed by doing that (by changing the port number).
I had solved this here : Changing project port number in Visual Studio 2013

If you use a different version of Visual Studio; you may also change the port number by project's Properties Window in Solution Explorer.

Answer 3

I just encountered and resolved this in VS2013 on Windows 7. It is a Web Application Project that doesn't use SSL. But when I examined the Properties Window (F4), SSL was enabled. Setting SSL to false resolved the issue.

However, when verifying before posting this answer, turning it back on did not cause a recurrence of the problem. So it might be that anything that writes to that preferences resolves the problem, rather than the details of what was written.

Answer 4

For me I tried a few of the above - run as administrator, check firewall.

For me it was the IIS Express configuration. A little bit of a "just get it working" fix without much investigation, but deleting the folder IIS Express is located under

C:\Users\UserName\Documents\iisexpress

Not sure what caused the issue for my VS2013 - but I am constantly flipping between VS2013 sites in IIS and IIS Express.

NOTE: When I forget to run VS2013 as Administrator, my Local IIS project gets inserted in the IIS Express applicationhost.config file, which fails to open the web project. Which is really frustrating.

Answer 5

Worked for me in VS2003 and VS2017 on Windows 8

1. Run the command in CMD with admin rights

   netsh http add iplisten ipaddress=::

2. Then go to regedit path [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\HTTP\Parameters] and check if the value has been added.

Answer 6

Open CMD as Administrator and paste below command as it is

netsh http add urlacl url=http://+:80/ user=everyone
