I was interested on how to host multiple domains on a single server using only one IP address. In my case I’m using IIS 6.0 on Microsoft Windows Server 2003. This can be accomplished using “host headers”. The host header distinguishes between various DNS names sharing a single IP address, allowing name-based virtual hosting.

If you are creating a new website in IIS. The third page in the “Web Site Creation Wizard” has a field titled “Host header for this Web site (Default: None):”.

If the website has already been setup in IIS. Right click on the website and select “Properties”. In the “Web Site” tab, click the “Advanced…” button. Edit the current entry for the website to add a “Host Header value:”.

I noticed the following error on SQL Server Enterprise Manager in Taskpad view:
Internet Explorer Script Error
An error has occurred in the script on this page.

Do you want to continue running scripts on this page?

I’m playing around with VMware and I created a Windows Server 2003 virtual machine. When I tried to activate windows over the net it failed (the web security appliance it blocking the connection). Microsoft gives the option to activate windows by phone, which I’ve never tried. I read this post about how to activate windows in less than five minutes: http://www.command-tab.com/2007/03/17/windows-xp-activation-in-5-minutes-or-less/ and I called thinking I was going to have to read an extremely long number to someone in a call center in India. To my surprise it was completely automated and didn’t take very long at all. I entered the extremely long longer on the keypad and the automated system read back to me the activation code. The code worked perfect and now my server is activated!
