Troubleshooting the Recipient Update Service (RUS) using Event Logs - Part 1

Having the RUS continue and just not stamp the addresses corresponding to the missing DLL is an idea that's been brought up, but since the problem is well documented, easy to identify, and easy to fix (unless you can't get access to the machine with the DLL on it), it's hard to justify making a hotfix to change the behavior, since changing the RUS to work this way runs the risk of destabilizing working code. They're keeping this in mind for the future, though.
