Unable to launch the IIS Express Web server

Unable to launch the IIS Express Web server.
Output from IIS Express. Failed to register URL for site. The format of the specified network name is invalid 0x800704BE.

The error occured beacause I had a IP binding to 192.168.0.50 added with: “netsh http add iplisten 192.168.0.50”

To remove IP-binding you can use the following command (requires admin permission)

1. Remove current ip listening: netsh http delete iplisten {ip-address}
2. Listen to all ip addresses: netsh http add iplisten 0.0.0.0
