proxying is enabled, oomads is installed, runas profile is a domain administrator. all domain controllers in all domains and all sites are being discovered and monitored.
in my AD Sites View and Topology diagram views, my sites appear as follows:
local AD site where SCOM server lives: green, expandable with domain controller objects underneath.
all remote AD sites: empty circles, nothing underneath
i thought i remembered reading about some override that is required to fully monitor remote AD sites, but i cant' find it in the current AD MP guide.
