Cannot start service w3svc on computer

Answer 1

This is probably a rarer case, but...

If you are using a custom AppPool Identity configuration be sure to check the AppPool is running. It may be turned off because credentials are invalid (usually due to an expired password). Update your credentials and start the AppPool.

Answer 2

Run cmd as administrator. Type iisreset. That's it.

Answer 3

In my case it was C:\Windows\System32\inetsrv\config\applicationHost.config which had an issue. I had a "system.web" section in this file which was causing the problem. Removed the section and everything started working

I know this post is old but I was getting this error. It turns out World Wide Web Publishing Service was disabled.

1. Click Start, type Services in the Search box, and then click Services.
2. Scroll until you find the World Wide Web Publishing Service that is stopped or disabled.
3. right-click the service, and then click Properties.
4. Click the Startup type list, and then click Automatic.
5. Click Apply, and then click OK.

Answer 5

I managed to solve after:

1. Ctrl+Shift+Esc = To open Task Manager
2. In the "Processes" tab locate the "IIS Worker Process" and finish it!
3. Run on cmd as an administrator. Type iisreset.

Ready! Be happy!

Answer 6

In my case, IIS suddenly stoped working, and after that Windows process activation service was unable to restart.

The solution to fix this was:

1. Find WAS service in the services tab of windows task manager
2. In context menu choose Go to process
3. Kill process (its name will be svchost.exe)
4. Restart Windows process activation service

Hope it will be usefull.
