httpd 2.0.54 VHost not working

["anand nalya" <anand.nalya@xxxxxxxxx>]

Hi,

I've Apache httpd version 2.0.54 on Redhat Linux Fedora 4. I'm trying to configure name based virtual hosts on it. Here are the relavent fragments from the httpd.conf:

DocumentRoot /var/www/html

NameVirtualHost 10.76.6.1:80

<VirtualHost 
10.76.6.1:80>
    DocumentRoot /var/www/html/sub
    ServerName 
sub.mydomain.com
</VirtualHost>

<VirtualHost 10.76.6.1:80>
    DocumentRoot /var/www/html/www
    ServerName www.mydomain.com
</VirtualHost>

The problem is that none of the virtual hosts is working.
For example, when I request a document with Hostname as 
sub.mydomain.com it returns files from the default root /var/www/html. If the virtual host were working, then it should return files from /var/www/html/sub.

Am I missing something??

Thanks in advance,
