file modified during boot not indexed

Hi Everyone, I have a problem with Splunk not indexing an XML file, modified during the windows boot process. Windows 10 creates an encrypted file during bootup which our powershell script parses and places the result in a location "c:\tpm" using a windows startup script. What I've tried - I added MAX_EVENTS to the props.conf and also on the sourcetype on the indexer for 100,000 lines because it is larger than the default limit. - If I open the xml file manually and add something into it, Splunk will pickup those changes. Since the file is not indexed without being modified while the SUF is running, I figured a setting might be needed. Any ideas? Thanks, wieljer
