Glenn,
Thanks for your reply.
In the 5 or so upgrades of the v2 branch that I have done I've yet to see an automated upgrade of the client. I have either manually upgraded or manually reimaged every computer. It's possible a handful of PCs upgraded on their own without me noticing, but I'm also certain that I regularly received a version mismatch error when trying to upgrade.
I understand issues with a new version and that's not the issue here. I'll be sure to monitor the next v3 upgrade to see if any clients are able to auto-update. Are there any firewall rules, permissions, etc. that might need to be changed? I have not had any unsolvable issues deploying applications, deploying images, or updating drivers aside from the client server version mismatch issues.
Best,
Joel
