If the Web address (URL) you type in the Address bar or click on a Web page doesn't work and you get a message that the site could not be found, now there's help. Internet Explorer can automatically search for any Web addresses that are close to the address you want. For example, you might type www.micrsoft.com, and the Web site wouldn't be found because it is misspelled. You can set Internet Explorer to search for any addresses.
If you don't want Internet Explorer to search for a similar address, click Never search.
If you want Internet Explorer to ask if you want it to search when an address fails, click Always ask.
If you want Internet Explore to search without asking first, click Always search.
If you want Internet Explorer to search for the address using a different "domain," select the Autoscan common root domains check box.
A domain is specified by the three-letter extension at the end of the address that tells you what kind of site it is. For example, if you type the wrong domain type, such as www.microsoft.org, Internet Explorer can check the root "microsoft" with other domains, such as .edu, .com, and .gov. It would suggest a match of www.microsoft.com.
