HI Igor
We have 14 server they all have the same setup and the same ports in different locations,im able to remote to all of them except that one, i don't use the default 3389 ,i use 6555 for all of them.
Beside i used to be able to remote to that server from my house "same network same provider same setup"! so i don't know what happened.
I didn't change nothing on the router and i tried to turn it off-on,same thing i could't remote.
This problem been happening for couple weeks now and i can't find a solution for it,
Even ,a couple employees that they used to remote for home to work on that server now they can't.
and some of them they still able to remote,even tho i did't change nothing not even my manager.
And i tried updating the server and my laptop i tried turn off the RDP and turn on the firewall and then turn on the RDP again also did't work,i tired alot of things but
im out of ideas i tried everything i can and i looked and googled all kind of things but i could't find anything that helped me with this .
im avoiding resting my router
in the beginning i thought is probably i run a different version of RDP and the server runs an older version,but i made sure to update both and now im running :
Shell Version 10.0.17134
Remote desktop protocol 10.5 is supported
and the server running :
Shell Version 6.3.9600
Remote desktop protocol 8.1 supported
but also when i remote from a different network it works fine on the same laptop so theres nothing that have to do with the version,so to be honest im out of ideas .
