Hi Team,

We have noticed one error event in the vent viewer. IIS config history path contains 11 files. hope all are the configuration backups.

we tried to reset the "Application host Helper service" but the files are not removing from the directory automatically.

Can somebody help on this case to clear the file without manual deletion?

Error:

The Application Host Helper Service encountered an error trying to delete the history directory 'C:\inetpub\history\CFGHISTORY_0000000066'. 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.

    Hi @Vishakhan K,

    According to Microsoft :

    Cause :

    This event is logged when the Application Host Helper Service encountered an error trying to delete the history directory.

    Resolution :

    Stop and restart AppHostSvc

    If the Application Host Helper Service (AppHostSvc) cannot delete a history directory, it will try to do so the next time that the service starts. Normally you do not have to take any action when this occurs. However, if the problem persists, you can stop and restart the service manually.

    To perform this procedure, you must have membership in Administrators, or you must have been delegated the appropriate authority.

    To stop and restart the Application Host Helper Service:

    1. Open an elevated Command Prompt window. Click Start, right-click Command Prompt, and then click Run as administrator.
    2. At the command prompt, type net stop apphostsvc.
    3. At the command prompt, type net start apphostsvc.

    @Yurong Dai-MSFT we have already tried this steps and the IIS config history file is not clearing after service restart. Do we need to follow any other steps to clear it without disruptions of running website configuration file?

    We don't want to manually delete the file from the inetpud directory.

    Can you help on this issue ?
