I have had SPS running for around 3 months in a medium server farm
cofiguration with one server hosting SPS and its related services
while
one server hosting SQL Server.

The installations were done based on the defaults provided by
Microsoft
Sharepoint Installation documentation.

The system has been running well.

I was checking the Application Event Log and came across around 10
entries spread over the past 3 moths whcih have the following
information

Source: Windows Sharepoint Services
Category: None
Type: Error
Event ID: 1000
User: N/A

Description:

#50070: Unable to connect to the database SPS01_Config_db on
<ServerName>. Check the database connection information and make sure
that the database server is running.

On Clicking the link (http://go.microsoft.com/fwlink/events.asp) in
description

addtional information that was shown was

File Name: ONETUTIL.DLL
File Version: 11.0.6568.0

The information from Microsoft Support that then came up said that
"There is no additional information about this issue in the Error and
Event Log Messages or Knowledge Base databases at this time"

Has anyone experienced similar errors getting logged.
