ويندوز سيرفر Windows Server حل مشكلة تاخير الدخول RDP Initial Connection slow
Slow Logins on Server Remote Desktop - Slow Connection to any host

RDP connection to remote machine is very slow

Another show-stopper is slow connection to Windows 10 machines over RDP. It doesn’t seem to happen with all machines but there are always some with issue. It doesn’t matter if connection is made from local network or over internet – when’ it’s slow, it’s just slow. Based on John D’s Tech Site article Remote Desktop slow problem solved it’s an old bug haunting around in Windows from version to version since Windows Vista.
For me it worked when I ran the command on both Windows 10 machines.

  1. Open command prompt in administrative permissions
  2. Run the following command: netsh interface tcp set global autotuninglevel=highlyrestricted
  3. Close command prompt


------------------------------------------
I was able to find the solution.
It's a result of aggressive auto-tuning of the connection which causes the delay on startup. Running the following should resolve your issue.
