We have one pc that once we:
Use Remote Desktop Connection to connect to \server
the DUO app launches (able to stay connected on this screen)
we complete 2fa
we get past DUO and see desktop
it immediately disconnects.
This is happening only on one PC. If I use the same AD user and DUO account on ANY other PC, it works fine. Also it happens to ANY user on this PC. Once we disable DUO, it works fine, stays connected with RDP
So it’s definitely an issue with this PC/this PC interaction with DUO. We have reinstalled duo, RDP is current, all Windows updates are current on client/server, all Dell update are current.
