Is the time on the epo server synced with the domain, I know I can get some daft connection errors when this is off
Thanks for responding Tony. I've checked the time against the other DCs in the AD site where the server is located and all are in sync.
I guess it must be doing some sort of succesful authentication to be able to browse the trusted domains, but I can't find any messages showing that success in orion.log. Maybe I need to be looking somewhere else?
Apologies to sound so clueless - I've had so few problems with EPO that I've never really had to dive into its innards like this before.
