Application Error ID: 1000 Source: Windows SharePoint Services 2.0

Symptoms:

The following event ID is logged (one or more times) in the Application log on the server:

Log: Application
Type: Error
Event ID: 1000

Source: Windows SharePoint Services 2.0

Description: #50070: Unable to connect to the database DatabaseName on SQLServerComputerName. Check the database connection information and make sure that the database server is running

Cause:

This issue may occur if the user account to which the Windows SharePoint Services Timer Service is configured to log on does not have permissions to the configuration database.

Resolution 1:

To resolve this issue, synchronize the Windows SharePoint Services Timer Service together with the new user account information. To do this, follow these steps:

1.    Start Windows SharePoint Services Central Administration.

2.    On the Windows SharePoint Services Central Administration page, click Configure virtual server for central administration under Server Configuration.

3.    On the Configure Administrative Virtual Server page, click Use an existing application pool, click the existing application pool that you are already using, and then click OK

Resolution 2: (work for me)

The "SharePoint Timer Service" service was running Log On As "NT AUTHORITY\NETWORK SERVICE".

This was changed to the service account to Log On As "Local System".

The problem is now gone.
