Actually no, they don't... strange thing but the patch erased all of the services that it couldn't find (go figure). Ended up doing a uninstall/reinstall and repatch at which point I switched the DB over to a backup I had made and magically everything started working again. And yes, it was installed as BESAdmin.

The only thing that I can think of is that I installed it using RDP and used mstsc instead of mstsc /console to RDP to the server, which completely escaped me until several hours into the ordeal.
