Solution for “Static compression is being disabled” error
Published Apr 29 2019 02:24 PM 13.4K Views

I saw “Static compression is being disabled” error in Event Viewer. It didn’t have any user-side effects but SCCM kept sending notifications about it.


The entire error description:

Error ID 2264: The directory specified for caching compressed content C:\inetpub\temp\IIS Temporary Compressed Files\ is invalid. Static compression is being disabled




Environment and Settings

  • IIS server is Windows Server 2012 R2
  • There are several websites hosted in the server
  • Anonymous Authentication is enabled. It uses App Pool Identity
  • Static Compression is enabled on both server and website level. Static Compression folder is C:\inetpub\temp\IIS Temporary Compressed Files
  • There are sub-folders for each website. The owner of these folders is Administrator



Setting application pool accounts as the owners of the sub-folders in IIS Temporary Compressed Files solved the issue. For example: IIS APPPOOL\ local account should be the owner of the folder.

In order to change a folder owner, follow the steps below:

  1. Delete the folder
  2. Create it with the same name
  3. Right click and go to “Properties”
  4. Select “Security”. Click “Advanced”
  5. Click “Change” for the owner field at the top


More Information

When a compression folder is created by IIS application pool identity which is part of the Administrators group, the folder is owned by the local Admin group. IIS checks ownership on existing compression folders when application pool starts. If it isn’t the owner, it attempts to delete and recreate the folder. Subsequent app pools may get caught in infinite loop attempting to delete and recreate the folder which causes the error mentioned above.
