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\domain.com is invalid. Static compression is being disabled
C:\inetpub\temp\IIS Temporary Compressed Files
Setting application pool accounts as the owners of the sub-folders in IIS Temporary Compressed Files solved the issue. For example:
IIS APPPOOL\domain.com local account should be the owner of the domain.com folder.
In order to change a folder owner, follow the steps below:
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.
