Apache Virtual Hosts Local Machine Help

Im trying to set up virtual hosts with apache for testing php on my local machine. I've searched the web all over and found the same instructions consistantly and have tried them numerous times but have been unsuccessful. First of all I'm having trouble determining where this "hosts" file is supposed to be located so I altered it and saved it in the first directory I found it... C:\WINNT\system32\drivers\etc Then made a copy of it to... C:\WINNT\system32 I changed the line from 127.0.0.1 localhost -to- 127.0.0.1 localhost examplesean.com I should mention that the hosts file I'm using does not contain the .sam extnsion that I found in tutorials the "hosts" file in fact has no file extension. I changed the httpd.conf file to contain: NameVirtualHost 127.0.0.1:80 <VirtualHost 127.0.0.1> ServerName examplesean.com ServerAdmin your_email@yourwebserver.com DocumentRoot "/www/examplesean" ErrorLog logs/error_log CustomLog logs/access_log common i created two directories in my apache htdocs directory one called www (as is similar to modwest) then a folder called examplesean with an index.html file. When I put http://examplesean.com into the browser I get the following error Not Found The requested URL / was not found on this server. ---------------------------------------------------------------------------- ---- Apache/1.3.19 Server at examplesean.com Port 80 Im running PHP4 with apache on a Windows 2000 professional OS. Any help would be greatly appreciated.
