256986 Description of the Microsoft Windows Registry
SYMPTOMS
When you use a Web browser to access a Microsoft Exchange Server using
basic (clear text) password authentication, you must enter the user name
and password manually.
If you have multiple Windows NT domains and the user account resides in a
domain different from that of the Microsoft Internet Information Server
(IIS) computer, you must enter DOMAIN\USERNAME for the user name.
WORKAROUNDWARNING: If you use Registry Editor incorrectly, you may cause serious problems that may
require you to reinstall your operating system. Microsoft cannot guarantee that you can solve
problems that result from using Registry Editor incorrectly. Use Registry Editor at your own
risk.
You can work around this issue by adding the following information into the
registry on the IIS computer with the Active Server Components. This will
allow users to enter only the user name and password and not the domain
name also.
- Start Registry Editor (Regedt32.exe or Regedit.exe as appropriate for your version of Windows NT).
- Go to the HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\W3SVC\Parameters key in the registry.
- On the Edit menu, click New Value, and then click String Value.
- Enter a new string value called DefaultLogonDomain with data of the DomainName (where DomainName is the name of the domain where the user
account resides).
- Quit Registry Editor. Restart all of the IIS services for the changes to take effect.
NOTE: There have been a few problems with this if your IIS computer is not a Primary Domain Controller or a Backup Domain Controller, or if you arerunning IIS 4.0.
If you are running IIS 4.0, follow these steps using the IIS Server Manager
for IIS 4.0:
- Right click the Default Web Site and then click Properties.
- Click the Directory Security Tab.
- In the Anonymous Access and Authentication Control Section, click the Edit button.
- Click to check the Basic Authentication (Password is sent in Clear Text) checkbox.
- Click the Edit button.
- Enter the Default Domain.
