XWEB: Setting the Default Logon Domain for IIS

• Microsoft Exchange Server version 5.0

IMPORTANT: This article contains information about editing the registry. Before you edit the registry, make sure you understand how to restore it if a problem occurs. For information about how to do this, view the "Restoring the Registry" Help topic in Regedit.exe or the "Restoring a Registry Key" Help topic in Regedt32.exe.

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.

WORKAROUND

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.

WARNING: Using Registry Editor incorrectly can cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that problems resulting from the incorrect use of Registry Editor can be solved. Use Registry Editor at your own risk.

For information about how to edit the registry, view the "Changing Keys And Values" Help topic in Registry Editor (Regedit.exe) or the "Add and Delete Information in the Registry" and "Edit Registry Data" Help topics in Regedt32.exe. Note that you should back up the registry before you edit it.

1. Start Registry Editor (Regedt32.exe or Regedit.exe as appropriate for your version of Windows NT).

2. Go to the following key in the registry: HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\W3SVC\Parameters

3. On the Edit menu, click New Value, and then click String Value.

4. 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).

5. Quit Registry Editor. Restart all of the IIS services for the changes to take effect.
