We do not see what you do. You are expected to provide more relevant information.

Hi , For SCCM related issue, it is recommended to ask your question on the System Center Configuration Manager Forums. 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.Tracy Cai TechNet Community Support
