IIS-APPHOSTSVC event id 9009

Question

Hi,

Our server keep generate a 9009 warning on the IIS-APPHOSTSVC:

The Application Host Helper Service encountered an error trying to delete the history directory 'C:\inetpub\history\CFGHISTORY_0000000205'. The directory will be skipped and ignored. Note that the directory may still get deleted in the future if the service restarts. The data field contains the error number.

I checked the file can be deleted automatically, but it will generate this warning on each cfghistory file.

And I tried to restart "apphostsvc" services several times, but the warning still occur.

Any idea?
