Hi,
we've got a simple configuration with 2 RDS servers for terminal sessions and another one for DC and connection broker. We have about 60 users and they connect to one of those 2 servers based on CB load-balancing. All servers are based on Windows 2016.
Each user redirects his (network) printer and one additional device connected by USB. Everything works fine, but yesterday we had a strange problem. One of RDS servers suddenly stopped accepting redirected devices (both: network printers and usb-devices). In logs i saw a lot of "Redirection of additional supported devices is disabled in policy" warnings. We see those warnings all the time, but not very often... during about 40 minutes there was a really lot of it (even few per one second). After that time everything back to normal (redirected devices started working again and no more warnings in logs).
What could couse that problem and what can we do to avoid that in future?
