To simplify as much as possible:
I have3 machines newly RE-installed ALL with Windows 10 PRO
Machine:
A) version 1903 and 2 shares, the C- and D-Hdrive
B) version 1909 and 1 share, the C-HDrive
C) version 1903 and 1 share, the C-HDrive
I'm logged on to all of them with my MS-account.
ALL machines can acces the SHARES on ALL the other machines - it is all combinations works well !
BUT when it comes to access via Remote Desktop, Oh, my ...
Machines B and C can NOT access A, but A can access BOTH B and C by Remote Desktop !
I've had this problem EVERY TIME I had to upgrade to a new version of Windows - lastly from 1803 to this crap 1903 and 1909. On one of them I even updated to 2004 and it was even WORSE so I downgraded again.
When I say "newly" installed I mean resetting Windows with clearing the whole disk - I beleave it's including formating too !
I have checked ALL the 'normal on user or super user level' procedures concerning Remote Desktop - nothing seems to work here !
... and remember it worked NICELY FOR YEARS with 1803 !!!!!
This problem is driving me CRAZY !
What is wrong here !
