Package Replication Begins Failing on Distribution Point
I recently had an issue where a DP started having failures for any package that was replicated to it. After checking out distmgr.log, it appeared that there was an error connecting to the root\MicrosoftIISv2 namespace. I toyed around with WMI permissions and DCOM for a little while and realized that the namespace had completely disappeared from the the server. If you go to c:\windows\system32\wbem and run the following command, then that will add the correct namespace back to WMI and package replication should begin working again.
