Remarks

It is not only about the "server" (machine name and appDomainappId), but also about an AppDomain, within a Process, on that server - because two AppDomains running at the same time on the same server (eg during a restart) are, practically, a LB setup.

Practically, all we really need is the guid, the other infos are here for information and debugging purposes.
