Report Server Windows Service stops running.

I have a test server running both 2000 and 2005 Reporting Services. Each day I have to restart the Report Server Windows service for the 2005 Report Server. This is the error I get when I try to access the Report Manager

The Report Server Windows service 'ReportServer$TSQL4' is not running. The service must be running to use Report Server. (rsReportServerServiceUnavailable) Get Online Help

After I start the Report Server Windows service using the Report Services Configuration tool I can access the 2005 Report Manager without errors. The windows service start up type is set to automatic.

I can not find why the 2005 version keeps going down.

Couple things to check:

1. Windows Event Viewer Application log

2. Report Server service log file -- ReportServerService*.log

There should be some "light" in 1 or both of these that will illuminate the underlying problem.
