Lately I've been trying to get host headers working with 2003 Server so I can have multiple websites on one IP address. I have followed multiple instructions, including the Microsoft one but can't seem to get it to work. I have tried using host headers for root domain (eg www.domain2.com) and for sub-domains for my default website (eg header.domain1.com) but I either get page not found, or more commonly it gets redirected to my default homepage. Any help with this would be greatly appreciated. Thanks
