After I upgraded from Windows 7 Ultimate to Windows 8 I'm receiving this error when I open a browser to my local site instance:
Service Unavailable HTTP Error 503. The service is unavailable.
After I receive the error, the applicationpool ASP.NET v4.0 is stopped.
I see the following line in the Event Viewer (local)\Windows Logs\Application:
"The Module DLL C:\WINDOWS\System32\inetsrv\compstat.dll failed to load. The data is the error."
I checked and there's no compstat.dll file in the \inetsrv folder. Apparently this file is for static compression, but don't know if I have enabled this or how to get the file installed!
I then checked what worker processes are started (followed instructions here: http://technet.microsoft.com/en-us/library/cc735182(v=WS.10).aspx):
- Click Start, click Control Panel, and then click Administrative Tools.
- Right-click Internet Information Services (IIS) Manager and select Run as administrator.
- In the Connections pane, select the computer name.
- In Features View, under the Feature Name column heading, double-click the Worker Processes management feature. A list of currently active application pools and worker processes will appear.
- The State column for the worker process will indicate Running if the worker process is running.
I don't see any running processes here.
I'm running Windows 8 with IIS8.0
