/Popular error caused by the 'nvidia firewall'........also........
You can correct the error by adding the NTAUTHORITY/SERVICE user to launch and activation permissions for app_filter with local launch and activation permissions.
To do this go to Administrative tools-component services, in the treeview expand component services-computers-my computer-DCOM Config, right click on app_filter select properties, on the security tab select customize for launch and activation permissions and hit the edit button to open the launch permissions page, click the add button to open the user and group selection page, click advanced to open the select user or group page, click the find now button then scroll down through the list of users and groups untill you find SERVICE in the list and highlight it then click ok to return to the select users or groups page, click ok again to return to the launch permissions page, now you should see SERVICE in the list of users and groups for app_filter, highlight SERVICE and check local launch and local activation in the permissions for SERVICE, click ok again to return to app_filter properties page and click ok again, now you should be all the way back to the component services page and the SERVICE user has permissions so you wont get any more DCOM errors............
nvtcp.sys is usually the culprit........... :thmbup: /
