Thanks for responding. I have seen people say DCOM errors doesn't matter at all but My problem was It sometimes does not shutdown and it keeps loading at shutting down. I let it load for 45 mins and it was still not shutting down. I do get 10 to 20 DCOM errors a day but when this happens it reports like 7k errors Also this error only happens when it is trying to shutdown. I had to hold the power button to turn off the pc everytime this happens.
