  • Question

  • Hi Experts,

    I'm facing the issue on windows server 2008 R2 SP1 and usually getting 4625 event logs on daily basis. upon checking the event logs found the below three logs on the row like 4625,4776 and 4673. 

    why the td_guest account is acting as mediator. Could you please help me out on the same.
