I can access my local dev site on my local pc, eg: http://mysite But I cannot access the live site, even though it works fine on other pc's: http://www.mysite.com The live site gives the error in Firefox: Server Not Found. Pinging www.mysite.com gives the error:"Ping request could not find host www.mysite.com" hosts file: 127.0.0.1 mysite I changed the hosts file to the following and rebooted: 127.0.0.1 mysitedev I'm running on XP, and have cleared the DNS cache using: ipconfig /flushdns I have verified the live site is up using: http://www.isup.me/ and the site loads fine using my phone. What could be preventing my local pc from accessing the live site?
