Hi, I suggest you ask this question in the Microsoft WSUS Forum for further discussion. The reason why we recommend posting appropriately is you will get the most qualified pool of respondents, and other partners who read the forums regularly can either share their knowledge or learn from your interaction with us. Thank you for your understanding. Regards,Mohammed Imtiyaz Ali
