安装Ex07SP3 Rollup1后控制台出现 error: 800706a

安装Exchange Server 2007 SP3 Rollup1后打开Exchange管理控制台出现以下错误信息：

Retrieving the COM class factory for remote component with CLSID {2B72133B-3F5B-4602-8952-803546CE3344} from machine xxxx failed due to the following error: 800706a

解决方法：

Is there any official answer for this? At least the release notes are not saying anything about changes on the firewalls. Or is it so, that Microsoft does not recommend to have firewall active on the Exchange servers?

edit:

To create the correct firewall rule:

1. Start new inbound rule
2. Select "custom" as a Rule Type
3. Select "All Programs" as a program
4. Protocol type: "TCP" Local port: "Dynamic RPC" Remote ports: "All ports"
5. To IP addresses: Any to Any
6. Action: Allow connection
7. Profile: "Domain" (was enough for me)
8. Name: Free text like: "Dynamic TCP incoming"
