|DCOM was unable to communicate with the computer ANOTHERSERVER.DOMAIN.lan using any of the configured protocol
So when you put another server on the network and just set it up for a specific purpose it may not open up all of the needed protocols in the firewall that it needs to correspond to the SBS 2008 box.
So here’s how to adjust the firewall to get the Dcom messages out of your event logs:
Event ID 10009 Source DCOM:
Check the firewall settings and enable the firewall exception rule
To check the firewall settings and enable the firewall exception rule:
- Click Start, and then click Run.
- Type wf.msc, and then click OK. If the User Account Control dialog box appears, confirm that the action it displays is what you want, and then click Continue.
- In the console tree, click Inbound rules.
- In the list of firewall exception rules, look for COM+ Network Access (DCOM In).
- 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
Right mouse click and enable the rule
Then to get the server to be able to query the name/model of the remote server enable the WMI in the inbound firewall rules as well.
Once you do that your server will report into the console and provide the hardware information on the Network/Computers tab.
