I know its windows feature, but the solution given on their website is also not allowing me to proceed to RAU installation. When I contacted windows administrators, they said its package issue, not windows.
The reason I am asking this question here is if someone faced this during RAU installation and how they fixed. Outside this community there are many examples and solutions and I don't want to perform hit and trial method in front of customer. I need solution which is tested by Netapp for their RAU.
