Delayed/Unreliable Logins with RDP Duo


Hi all, just installed Duo on a machine for two-factor auth, however it seems to have made RDP unreliable. Attempting to connect often results in the session setting at “initialising” before proceeding to setting up a secure desktop. On the occasions that there is no delay or failure to initialise, it works perfectly fine.

The only thing I haven’t done is reboot the machine as it’s currently in use at the business.

Any ideas as to why RDP now intermittently doesn’t initialise correctly? Do I just need to reboot?


Is this before or after login + Duo 2FA?

Are there any errors or warnings in the “Microsoft-Windows-TerminalServices-SessionBroker/Operational” event viewer log for a delayed connection?
