I've had this happen a couple times now. If I reboot a 11.2 patch 3 Prognosis Monitor when it comes back up it displays in my Prognosis Manager as "Unlicensed". I verify the license is correct, and exists. Restarting Prognosis on the Monitor does not fix this. I also tried removing and reading the Monitor from the Prognosis Manager Network configuration. The Monitor appears to be functioning, but I cannot view it or any of it's monitored devices from the Mananger.
