Explanation:
w3wp.exe an Internet Information Services (IIS) worker process is a windows process which runs Web applications, and is responsible for handling requests sent to a Web Server for a specific application pool. W3wp.exe process will not be started automatically after App tier reboot or IIS restart or application pool restart. w3wp.exe will be launched once the first request is made to the TFS Application.
Solution:
1. Try accessing TFS application once http://tfs:8080/tfs. See whether the w3wp.exe is available in "Windows Task Manager" --> "Processes Tab"
2. You can configure Worker process started automatically by adding startMode attribute to TFS application pool to AlwaysRunning in your applicationHost.config
<applicationPools>
<add name="Default App Pool" startMode="AlwaysRunning" />
</applicationPools>
Solution 2 will work for IIS 7.5 or newer
