SUMMARY
By default, Internet Information Server (IIS) validates an unqualified user logon ID against either the local computer's user database or the domain which the server is a member of. This article describes how to configure IIS to validate the unqualified user logon against all trusted domains and the user accounts database.
MORE INFORMATION
To configure IIS to validate the unqualified user logon against all trusted domains and the user accounts database, use the appropriate method:
IIS 4.0 and IIS 5.0
Method 1
- Start the IIS Microsoft Management Console (MMC).
- Right-click the desired Web site, and then click Properties.
- On the Directory Security tab, in the Anonymous Access and Authentication Control section, click Edit.
- Click Edit for Default domain for basic authentication.
- In the Domain Name text box, type a single backslash \.
- Click OK three times to return to the Internet Service Manager MMC.
Method 2
You can also set the DefaultLogonDomain parameter for IIS 4.0. This parameter has been moved to the metabase for IIS version 4.0. To do this, run Adsutil.vbs from a command prompt, using the appropriate syntax below (depending on whether you want to set DefaultLogonDomain for all FTP sites, only the default FTP site, or other sites):
- To set DefaultLogonDomain for all FTP sites, run the following command:
adsutil set msftpsvc/DefaultLogonDomain "DomainName
- To set DefaultLogonDomain for only the default FTP site, run the following command:
adsutil set msftpsvc/1/DefaultLogonDomain "DomainName
- To set DefaultLogonDomain for any other site, use the same syntax as the default FTP site above, but change the "1" parameter to the appropriate service number.
