XWEB: Outlook Web Access Stops Working After Running DCPROMO

 * }

Q259640

-

The information in this article applies to:


 * Microsoft Outlook Web Access, version 5.5 Service Pack 3
 * Microsoft Exchange Server, version 5.5 SP3

-

SYMPTOMS
Users may be unable to log on to Outlook Web Access (OWA) after the OWA Windows 2000 member server is promoted to a Windows 2000 domain controller. The following error message may be displayed:

HTTP 401.1 - Unauthorized: Logon Failed.

Administrators should still be able to gain access to their mailboxes by using OWA.

CAUSE
This issue can occur because domain users do not have the Log On Locally right by default on Windows 2000 domain controllers, and the Log On Locally right is not transferred to the domain controller's Active Directory object during promotion.

RESOLUTION
To resolve this issue, grant users the Log on Locally right:


 * 1) Click Start, point to Programs, point to Administrative Tools, and then click Domain Controller Security Policy.
 * 2) In this Microsoft Management Console (MMC), click Windows Settings, click Local Policies, click User Rights Assignment, and then double-click Log On Locally in the right pane.
 * 3) Add the OWA users.
