Problem with web sharing

Hi all,

For the longest time, I have successfully used IIS Websharing to furnish
directories to my team. Recently, querys to the share would not resolve. I
have gone so far as to remove / add IIS, and WebDAV again. It did not help.

Currently, this is what is happening:

Web-sharing enabled on c:\myTest on MyServer
Queries to http://MyServer will generate an HTML-view of the file contents
Queries to \\MyServer will not resolve ( "The network path was not found" )

Steps taken:
Added IUSR to the Permissions list ( full control )
Double-checked the settings; Directory sharing is checked in IIS manager
Enabled Anonymous and Integrated Windows Authentication.

Platform:
Windows Server 2003 and IIS6. ( all recent updates )

I know I could simply share this directory the conventional way, but since I
use host headers to give shares distinctive roots, I really need to use IIS
for sharing directories.

Please help!
Thanks!
