Hi,
If the “Network Service” account did not have proper rights(Read access) on the specified config file, you will receive this error message.
I have Convert the CACLS command to ICACLS command, please try the following command:
ICACLS "%SystemDrive%\Windows\System32\inetsrv\config" /grant "Network Service":R
ICACLS "%SystemDrive%\Windows\System32\inetsrv\config\administration.config" /grant "Network Service":R
ICACLS "%SystemDrive%\Windows\System32\inetsrv\config\redirection.config" /grant "Network Service":R
ICACLS "%SystemDrive%\inetpub\ftproot" /grant "Network Service":(M,W)
If problem still persists, please update here.
