IIS Error – W3SVC Not Starting – Event ID 115

Did your personal IIS stop working recently — the one you run on XP perhaps? Did you get the following error in your event logs?


Event Type: Error
Event Source: W3SVC
Event Category: None
Event ID: 115
Date: 4/23/2006
Time: 12:28:08 PM
User: N/A
Computer: F4005
Description:
The service could not bind instance 1. The data is the error code.

For additional information specific to this message please visit the Microsoft Online Support site located at:

This error is normally the result of another application/service on your machine listening on network Port 80.

But you’re sure you don’t have any other web servers, etc. running, right? This can be frustrating to troubleshoot. So, before you uninstall everything one by one, be sure to check Skype. As Skype gains popularity, my guess is more and more people will be getting this error and scratching their heads.

To stop the error from occurring in IIS, go to “Tools”, then “Options…” in your Skype applications. In the “Connection” section, be sure to UNCHECK “Use port 80 and 443 as alternatives for incoming connections”.

Click “Save” and restart Skype. Restart IIS. You should be good to go.

I hope this helps someone!

  1. Hi,
    Great work, it was Skype causing the prblem by registering port 80 before iis on my machine.

  2. I only just discovered this today while debugging in Visual Studio, which gave a lot of cryptic errors. Thanks for putting this article online – it save me pulling what little hair I have left out. 🙂
