>>>Hi,
>>>
>>>I am trying to understand what is a better choice for an Intranet ASP.NET application? (note that not Internet but Intranet): Web Site or Virtual Directory.
>>>
>>>When I go to the Web server, I can add a Web Site to the Web Sites Item in the IIS. Or I can expand Web Sites and then right-mouse click on Default Web Sites and Add Virtual Directory to the Default Web Site. I really don't understand the difference and therefore don't know which one has an advantage for ASP.NET intranet application.

>>Is IIS currently using the default web site for content other than your app? If so it might be preferable to create a new web site on a different IP address - that way you can start and stop it, control access etc without affecting the default site.

>After reading whatever I could find on the web about new web site vs. virtual directory, I agree with you that I need to create a new web site. The only thing I don't understand is what IP address to enter when creating new web site? How do you determine what IP to choose/enter?

Add a suitable additional static TCP/IP address using the 'Advanced' button on the Windows TCP/IP Properties form.
In IIS create the new website, open it's Properties page, click the 'Advanced' button in Web Site/ Web Site Identification and edit the IP address to use the required address.
