Problems accessing non-local disks

[OwenWatson]

I have an install of the latest xampp/apache that decided to stop accessing web documents that were on the fileserver elsewhere on the network. Here's the vhost lines:
<VirtualHost 202.36.162.18:80>
ServerName test.rsnz.org
DocumentRoot W:/test
ServerAdmin webmaster@rsnz.org
ErrorLog logs/test.rsnz.org-error_log
CustomLog logs/test.rsnz.org-access_log common
</VirtualHost>
Whenever I try and access test.rsnz.org I get a 403, which goes away if I change documentroot to a local disk.
Changing DocumentRoot to the UNC path (//Fileserver/web/test) makes no difference.
apache is running as a console app under a domain admin account, so permissions shouldn't be a problem (indeed, accessing the paths above is no problem in Explorer).

Any clues on how to sort this out? The access log and error log give no extra clues.

remove these two lines save and restart apache
ErrorLog logs/test.rsnz.org-error_log
CustomLog logs/test.rsnz.org-access_log common

Did that: no difference.

Found it: I put this in http.conf:

<Directory "W:/test">
Options FollowSymLinks
Order deny,allow
Allow from all
</Directory>
