DefaultDomain Metabase Property (IIS 6.0)
The DefaultDomain property specifies the default domain for logon to an SMTP server. If this value is not specified, the default domain is the domain name controlled by the computer, if the computer is a domain controller. If the computer is not a domain controller, the default domain is the computer name.
You can configure this property at the following locations in the IIS metabase.
