Opening files on a mapped drive

I'm developing an application in asp.net on my web server.  It will be used to display the status of the fax log files on a Castelle fax server.  How can I open these log files on the fax server from my web server?  I'm running windows 2003 server.  I can map the drive on the web server to the fax server.  Can I create a Virtual Directory or an alias??  Any help is appreciated!
