Symptoms
When you try to install or upgrade to Microsoft SQL Server 2008, the results of rule checks may be logged incorrectly in the System Configuration Check Report (SystemConfigurationCheck_Report.htm) file and in the Detail.txt log file. For example, the results of the Engine_UserHasNotDefinedSchemaSysCheck rule check may be logged as “Not Applicable.” This occurs even though there is a schema named “sys” in one of the SQL Server databases.
Note This rule check determines whether the user has defined a schema called ’sys’.
Resolution
This problem can occur if the rule is evaluated by using a three-state rule check in SQL Server 2008. A three-state rule check is a rule that can return a Passed, Failed, or Warning status.
