Hello everyone, i created a portal site with hostname,now i could not access that site because of hostname so i extended the webapplication without hostname and now it is working fine but some of images and documents uploaded in that application are not showing up when iclick the image it is redirecting me to the old site with hostname and giving me error"internet explorer cannot display" so i think i have to do something with the DNS server(like adding hostname) can anyone guide me as i do not know how to add them ? thanks in advancelahari

Assuming you are using DNS installed on Windows server and have the right security priveledges, take a look at the Technet article below. http://technet.microsoft.com/en-us/library/cc779029(WS.10).aspxPaul Stork SharePoint Server MVP
