 and APPID
{61738644-F196-11D0-9953-00C04FD919C1}
 to the user IIS APPPOOL\DefaultAppPool SID (S-1-5-82-3006700770-424185619-1745488364-794895919-4004696415) from address LocalHost (Using LRPC). This security permission can be modified using the Component Services administrative tool.

Hi Ankush,
Based on my research, Event 40968 is caused by an invalid authentication request, which we can ignore, please refer to a related thread below:
Event id 40968 - what does this mean?

As for Event 10016, we can try to resolve it by
using the Component Services administrative tool to update the application security policy to allow the requested operation to complete.
