Newbie needs help with load balancer module

[mickscool80]

Hi Friends,
I am trying to learn load balancing in apache 2.2.2 with win2K,but I get this error message:

Code:
Invalid command 'BalancerMember', perhaps mis-spelled or defined by a module not included in the server configuration

I researched and came to know,I need to have this module uncommented,but I cannot see anything like this in my httpd.conf file:

Code:
LoadModule proxy_balancer_module modules/mod_proxy_balancer.so
If I type it there,then I get this error message:

Code:
Cannot load C:/Program Files/Apache Group/Apache2/modules/mod_proxy_balancer.so
into server: The specified module could not be found.

Here's my httpd.conf file part:

Code:
NameVirtualHost *
<VirtualHost *>

ProxyRequests Off
ProxyPass /test balancer://cluster
ProxyPassReverse /test balancer://cluster

<Proxy balancer://cluster>
BalancerMember [192.168.0.1...]
BalancerMember [192.168.0.2...]
</Proxy>

# ErrorLog C:/apache.log
</VirtualHost>

So,can somebody please tell me how I can install that module?Any help would be appreciated.
Thanks
