vhosting problem

I am trying to serve different websites in separate folders under the root www folder

<VirtualHost *>
DocumentRoot "c:/phpdev/www"
ServerName www.chcisp.com
</VirtualHost>

<VirtualHost *>
DocumentRoot "c:/phpdev/www/bob"
ServerName www.bob.chcisp.com
</VirtualHost>

I did the cname alias with zoneedit.com -My DNS server
www.bob.chcisp.com is aliased to www.chcisp.com

When I start Apache I get a warning ??
Virtual Host overlap on port 80. The first has precedence.

I can see my main web site but never any of the others.
The Virtual Host examples looked simple enough, but I guess not for me. I've tried many different Vhosting comments made on this site but can't get it to work . If I use http://www.chcisp.com/bob without using virtual hosting it works o.k. Anyone have some helpful suggestions.

A guess
try
]

<VirtualHost *>
DocumentRoot "c:/phpdev/www/bob"
ServerName bob.chcisp.com
</VirtualHost>

not the best help

Because bob.chcisp.com and www.bob.chcisp.com are not DNS resolvable.

Thanks for the help!
Thinks I figured out my problem.
NameVirtualHost didn't have the star behind it

No yet.

When you want Apache to listen to all available NICs (including the ones that map to 127.0.0.1, 192.168.0.1 and 12.34.56.78). Or when you have dynamic IP, then you should use NameVirtualHost *.

Your problem is, your domain didn't have wildcard enabled. bob.chcisp.com and www.bob.chcisp.com also not lookup'able. You might be able to look it up internally with /etc/hosts but people from elsewhere can't.
