HTMP/PHP opening remote text document in browser not working Apache( IIS)

I have had a basic intranet working fine for a few years running on an IIS server. Our ERP server drops automated reports into a shared (read only) location the users can access on the LAN. 10.0.1.1xx

To make things simpler, i created a web page which links to named documents with better titles etc in an alphabetical list.

These opened and displayed in a basic webpage (which was all that was wanted) using

  <a href="file://10.0.1.1xx/PRT/01PRINT105" target=_blank>Purchase Report</a><BR>

Everything works fine and still does, from the old server.

I then copied the Intranet to an Apache server running on a synology NAS drive and nothing works.

Any help recommendations gratefully received. No error messages displayed, just a page that doesn't do anything.

PHP or HTML
