I am getting the following error in the event logs when my server reboots
nightly.

Event Type: Error
Event Source: Service Control Manager
Event Category: None
Event ID: 7024
Date: 5/27/2005
Time: 3:05:18 AM
User: N/A
Computer: test01
Description:
The Certificate Services service terminated with service-specific error
2148204801.

I am able to connect to the web server using https with out issue.
Does anyone have any suggestions as to what is causing this.

The system has been running with service pack 4 for quite awhile without
error.

Thank,
Jeff
