Anonymous User Account
Use this dialog box to set the Windows NT user account used for anonymous connections. By default, the server creates and uses the account IUSR_computername.
Username
Type the name of the anonymous account you created with the Windows NT User Manager for Domains utility in this box.
Password
Type in the anonymous user account password in this box. When you installed the server, Setup created the account IUSR_computername in Windows NT User Manager for Domains and in Internet Service Manager.
Note
Enabling automatic password synchronization disables this box. The password is used only within Windows NT; anonymous users do not log on by using a user name and password.
Enable Automatic Password Synchronization
When you create a new anonymous account, you must make sure that your Web site and Windows NT password settings are identical. Select this option to enable your Web site to automatically synchronize your anonymous password settings with those set in Windows NT. This option is enabled by default if the anonymous account exists on your Web site, and not on a remote computer.
