From the error message, it indicates some folder is missing. The ideal way to find out which directory was invalid is to use Process Monitor tool that records the real time file system activity in this case.

Based on our experience, we first checked what the TEMP and TEM folder were pointing to

1. Right-click My Computer -> Properties -> Advanced tab -> Environment Variables -> Select the TEMP variable under System variables -> Edit

It may be pointing to "%Windir%\Temp”.

2. Check if the location %Windir%\Temp is present there.

If not, create the Temp folder on C: drive.

3. Reset IIS

Then, it still failed to start on. We checked the Application Event log. Although it was still the Event 1310, the detail was different. Now it is “Access is denied”.

Use Process Monitor tool to find out which directory was invalid.

Create the %Windir%\Temp that TEMP and TEM variable under System variables are pointing to.

Add the Full control permission for Network Service account to the folders:

· %Windir%\Temp

· %Windir%\Microsoft.NET\Framework\v2.0.50727\Temporary ASP.NET Files
