Trying to play with apache virtual hosts, getting access forbidden errors

I'm just messing around with virtual hosts on my XAMPP + Apache install on Windows to make it work so that http://disko.local redirects to a folder in my PC where the project's files are stored.
I've added the following lines to C:\Windows\System32\drivers\etc\hosts:

127.0.0.1       localhost
127.0.0.1       disko.local
::1             localhost

And then proceeded to edit the file X:\xampp\apache\conf\httpd.conf to add these lines at the bottom of the file (do they have to be in any special place?):

# My custom vhosts
NameVirtualHost 127.0.0.1

<VirtualHost 127.0.0.1>
   DocumentRoot "X:\Work\Web Development\Projects\disko\serverroot"
   ServerName disko.local
</VirtualHost>

With a fast search through the file I determined that that was the only vhost present in the file.

Then I restarted Apache, opened my browser and tried to load the page http://disko.local/artists.html. This is the error that appeared:

Access forbidden!

You don't have permission to access the requested object. It is either
read-protected or not readable by the server.

If you think this is a server error, please contact the webmaster.

Error 403

disko.local 10/22/11 16:06:58 Apache/2.2.21 (Win32) mod_ssl/2.2.21
OpenSSL/1.0.0e PHP/5.3.8 mod_perl/2.0.4 Perl/v5.10.1

I tried adding a .htaccess file containing the string allow from all but that was of no help.

Here's what the error.log file says:

[Sat Oct 22 16:06:58 2011] [error] [client 127.0.0.1] client denied by server configuration: X:/Work/Web Development/Projects/disko/serverroot/artists.html

What am I doing wrong? Do I have to add anything to the VHost definition? Thanks in advance.

P.S.: Here's the version of Apache, in case it's needed:

X:\xampp\apache\bin>httpd.exe -v
Server version: Apache/2.2.21 (Win32)
Server built:   Sep 10 2011 11:34:11
