CAUSE
By default, Integrated Windows authentication is disabled if you install Microsoft Windows Server 2003 Service Pack 1 (SP1) as part of a slipstream installation of the Windows Server 2003 operating system. However, Integrated Windows authentication appears to be enabled in Microsoft Internet Information Services (IIS) Manager.

Integrated Windows authentication must be enabled on IIS for Speech Server to contact the Speech Engine Service (SES).



RESOLUTION
To resolve this issue, manually disable and then re-enable Integrated Windows authentication in IIS Manager. To do this, follow these steps:
 * 1) In IIS Manager, click Web Sites, click Default Web Site, and then select SES.
 * 2) Right-click SES, and then click Properties.
 * 3) In the Properties dialog box, click the Directory Security tab.
 * 4) On the Directory Security tab, click Edit next to Authentication and Access control.
 * 5) In the Authentication Methods dialog box, click to clear the Integrated Windows Authentication check box. Then, click to select the Integrated Windows Authentication check box again.
