If you have been installing SharePoint you have probably also seen and fixed the DCOM 10016 error. This error occurs in the event log when the SharePoint service accounts doesn’t have the necessary permissions (Local Activation to the IIS WAMREG admin service).
On a Windows Server 2003 or Windows Server 2008 machine you would just fire up the dcomcnfg utility and enable Local Activation for your domain accounts. But for Windows Server 2008 R2 you cannot do this, the property dialog is all disabled due to permission restrictions.
Read here how to solve this. Fortunately I found this blogpost quickly. Thanks Wictor!
