Alias for a maped network drive

I am trying to make [domain.com...] pull a php file from a mapped network drive. Here is what I have found and done so far:

I am running a server 2003 domain

Temporarly till this works, Apache service runs as administrator

The administrator has L: mapped in its profile and I can access and execute the remote files and everything in the Apache2 directory.

Here is my alias:
Alias /lan/ "L:/"

Here is my Directory:
<Directory "L:/">
AllowOverride None
Order allow,deny
Allow from all
</Directory>

The apache service will not start unless I changethe directory to this:
<Directory "C:/">
But domain.com/lan still does not work

Any Help would be awesome!
