We have a server setup as an IIS box and have some static pages with a few asp pages that handle the form submissions. The asp is really vbscript that sends a CDO message.

When moving these pages to the new server the form will not submit, it gives a 500 error and the following shows in Event Viewer:

Error: The Template Persistent Cache initialization failed for Application Pool 'DefaultAppPool' because of the following error: Could not create a Disk Cache Sub-directory for the Application Pool. The data may have additional error codes..

I can't seem to find any info on this anywhere... I was thinking it may have something to do with the fact that we created this server from an image of another server.

Server Info:

Windows 2008 R2 Datacenter SP1

Hosted on Amazon EC2

Thanks for your help in advance...

having same problem with an old asp shopping cart, site works for 10-15 minutes then 503. The folders mentioned in the answer not exist on the server – dvdmn Dec 26 '14 at 20:26

I think this has to do with some permission settings, check if IIS_WPG and NETWORK SERVICE has access to the following folders:

  • %systemroot%\Help\IISHelp\Common
  • %systemroot%\System32\Inetsrv\ASP Compiled Templates*
  • %systemroot%\IIS Temporary Compressed Files

None of those folders exist – VinceM Oct 3 '12 at 18:57
