Check the firewall settings and enable the firewall exception rule

To check the firewall settings and enable the firewall exception rule:

3. In the console tree, click Inbound rules.
4. In the list of firewall exception rules, look for COM+ Network Access (DCOM In).
5. If the firewall exception rule is not enabled, in the details pane click Enable rule, and then scroll horizontally to confirm that the protocol is TCP and the LocalPort is 135. Close Windows Firewall with Advanced Security.

 

on Node1  “COM+ Network Access (DCOM In)” is disabled
