IIS Dispatcher not caching:Unable to open temporary file

03-05-2019

Good Morning,

I installed dispatcher-iis-windows-x64-4.3.2 and AEM 6.2 SP1 on my win10 laptop following Installing Dispatcher .

I'm able to access page http://localhost:8000/content/we-retail.html normally. But the problem is that none file is cached.

I'm sure I have given write access to  Application Pool User (AEM in my case) for docroot.

Based on the log, error is "Unable to open temporary file C:\inetpub\wwwroot\aem\content\we-retail.html_PJNAa21612: Permission denied" . Cannot understand what happened to my server. Any idea?

This permission issue is resolved by granting write permission to IUSR by referring to AEM Dispatcher config for IIS missing IUSR permission

Shouldn't the documentation be updated accordingly as the user Brent Landry mentioned?  It cost us much time debugging this issue.

Hi JaideepBrar,

Thanks for your update!

I can see the process w3wp.exe is running with user AEM. and the pid is the same with pid in log.

By reviewing folder property of "C:\inetpub\wwwroot\aem", I can see user AEM already has full access to it.

After clearing the folder, even restarted by system. I still has the same issue, error is in below:

Looks like a permissions issue. Can you check the if the user running the dispatcher process has full rights on the "C:\inetpub\wwwroot\aem\" folder.

If this is still an issue, try deleting everything under "C:\inetpub\wwwroot\aem\" and try again.
