Bug #: 50003386 (SQL Hotfix)

SYMPTOMS

You install Microsoft SQL Server 2008 Reporting Services. A client makes an anonymous request to the Report Server Web service. The anonymous request is the initial request to the Report Server Web service. In this scenario, the client may receive an error message that resembles the following:
HTTP 401 Unauthorized
After the client receives the error message, other clients cannot connect to the Report Server Web service.

Note This problem can occur when the Report Server Web service receives the initial request directly or by using Report Manager.

CAUSE

This problem can occur if the user account that makes the initial request does not have read permissions on the following registry key:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft SQL Server\MSRS10.MSSQLSERVER
If the user account that makes the initial request does not have read permissions on the registry key, the Web service is not initialized correctly.
