I've been using remote desktop in the past with no issues, It's been a year since I used it, today I decided to connect using it but it's super slow (minutes) trying to connect. It's fast to ask for the credentials, then hangs for a long time, once connected it's fast again.
The remote allowed any version of remote desktop, I did a test where I could connect without using NLA (Network Level Authentication) and it was fast, no delay and was able to login though the GUI.
This last attempt closing the RDP (connected using NLA) seemed to have the disconnect hanging as well (caused windows explorer to hang (desktop, other apps)). Until I ended the rdp task (and after about 10 seconds things started to respond again).
Win10X64 Pro.
I've tried connecting to different targets on the network, all the same.
Any idea on what could have happened to cause this or how to fix?
