Start the IIS Microsoft Management Console (MMC). 2. Right-click the desired Web site, and then click Properties. 3. On the Directory Security tab, in the "Anonymous Access and Authentication Control" section, cclick Edit. 4. Click Edit for Default domain for basic authentication. 5. In the Domain Name text box, type a single backslash "\" (without the quotation marks). 6. Click OK three times to return to the Internet Service Manager MMC.
