Make sure your Windows Firewall is configured to
- allow outbound traffic (on your client) on port 135
- allow inbound traffic (on your certificate server) on port 135.
Inbound traffic is most likely being blocked since that is the default setting.
To verify you have solved the issue by opening the firewall ports, do next:
1. Open Task Scheduler;
2. Expand Task Scheduler (local)\Task Scheduler Library\Microsoft\Windows\CertificateServicesClient;
3. Run the SystemTask and the UserTask;
4. Wait for a few minutes. Then recheck your Eventlog to verify the error does not appear.
