Virtual Hosts don't work

Hi,

I have vhosts turned on in httpd.conf

# Virtual hosts
Include conf/extra/httpd-vhosts.conf

In httpd-vhosts.com, I have following entries.

NameVirtualHost *:80

<VirtualHost *:80>
ServerAdmin weblogician@yahoo.com
DocumentRoot "C:/Programs/apache/httpserver/htdocs"
ServerName vishnugupta.dnsalias.com
ServerAlias vishnugupta.dnsalias.com
ErrorLog logs/vishnugupta.dnsalias.-error_log
CustomLog logs/vishnugupta.dnsalias.com.-access_log common
</VirtualHost>

<VirtualHost *:80>
ServerAdmin jivanrashmi@gmail.com
DocumentRoot C:/Programs/apache/httpserver/htdocs/JivanRashmi
ServerName www.jivanrashmi.org
ErrorLog C:/Programs/apache/httpserver/htdocs/JivanRashmi/logs/
jivanrashmi.org-error_log
CustomLog C:/Programs/apache/httpserver/htdocs/JivanRashmi/logs/
jivanrashmi.org-access_log common

<Directory c:/Programs/apache/httpserver/htdocs/JivanRashmi/>
AllowOverride All
Order Allow,Deny
Allow from All
</Directory>

</VirtualHost>

As soon as I turn on the vhosts, the server doesn't start. What am I
doing wrong?

Thanks,
Gaurav
