Re: [FSSO] - Users disappear from logon users list
FSSO does workstation check (check if user still logged in) via WMI, by requesting "username" from computersystem.
However, with RDP, this value is empty. This is what triggers the de-authentication. (Collector things the user logged off)
This should be fixed since FSSO version 5.0.0257 (different method of checking for RDP). Check your version of FSSO, and upgrade if needed.
