I've not experienced this particular problem yet, although I am sure I will as I am about to start performing remote verifies! (just waiting for my Flexclone license on my secondary to arrive!).
Exchange verification in general though has always been a pain in the proverbial bottom for me. Mainly because of the IO /performance hit on the filer, and my new problem that i can't seem to disable verify on any scheduled backup job - so its running after every full backup no matter what I tell the damn thing! Even if I remove all the verification settings from the schedule task, it still runs ESEUtil after a full backup.
Whereas if I run a full backup without verify via the SME interface, then it works fine! Just the scheduled tasks don't work as intended.
This is just one problem though with SME6 and SDW6.3. I've been using SME for some years now and there is always a problem somewhere - pretty much every month I am dealing with something new that requires a hidden P1 version of SME, or the OnTap VSS hardware provider fails and I have to restart my Exchange server.
I'd be interested to know if you ever find a solution to your remote verify issues!
