I have a Samba share that I've created from a Linux box. I've mapped this
sucessfully to drive in Windows 2003 server. I'm also able to read/write to
it under Windows explorer just fine. It's using user security so I have to
enter the username and password defined in the Linux box when connecting to
this share.

I then mapped a virtual directory under IIS to the UNC name of this Samba
network share (\\MachineName\ShareFolder) and saved the Samba connection
login.

This is when the problems began. Now whenever I goto my browser and type
the url to that folder I get an error 500. The IIS log file shows this:

2005-02-03 14:29:11 192.168.1.150 GET /test/test.jpg - 81 - 192.168.1.150
Mozilla/4.0+(compatible;+MSIE+6.0;+Windows+NT+5.2;+.NET+CL R+1.1.4322) - 500
16 1326 15

"/test/" is the virtual directory that I've mapped the Samba share to.

Is this caused by a permissions problem? I don't see any other reason for
it. I'm not accessing a script, just a static file.
