The GetParentRuleGroup method does not return the correct rule group objects in Microsoft Operations Manager 2005

The Microsoft Operations Manager (MOM) 2005 Software Development Kit (SDK) .NET Framework class libraries include the GetParentRuleGroup method. However, this method does not return the correct rule group objects. For example, when you use the GetParentRuleGroup method to return an active RuleGroup object, the method may return a deleted RuleGroup object. If only one object is active, the GetParentRuleGroup method may return the last deleted object instead of returning the active object.

This problem may occur when the Rule or RuleGroup object has one active parent rule group object and one or more parent RuleGroup objects that are marked as "Deleted". In this situation, a deleted RuleGroup object may be returned instead of the correct parent RuleGroup object. The GetParentRuleGroup method cannot correctly process instances where a rule or a rule group has multiple parent RuleGroup objects.
