view folder contents in IE6

[gob]

I have a web application that opens a shared folder on a server in an Inline
Frame (<IFRAME>)
I set the contents if the IFRAME using
location.href=file://<servername>/folder/ with clientside vbscript.
This has been working fine in IE5, but since I upgraded to IE6 i get 'The
page cannont be displayed' in the IFRAME.

Any Ideas?

Thanks
