Hope you are well.
In my client's network, we have 3 windows 10 pro PCs. He used to connect to his PC in his office room from either of the other 2 in the building via remote desktop. That was until yesterday where the pc installed the kb5005565 update.
After the update, he went along with his day and tried to connect to the office PC but it returned the following message:
The strange thing is that he can control the other 2 PCs from his and the other 2 can connect fine with each other!
I tried and read everything (turn off the firewall, change the port for RDC, change the port to decimal, check services, policies, check hosts, check ping, check if it was allowed through the firewall, and more...) recommended as solution to no avail. I even unistalled the update but the problem persists.
I am literally one step from going crazy here. i can't find what is wrong all the sudden and i do not know what else to try so i can help him.
There is no file server or any server on the network. Roughly the network is composed by the isp router where 3 switches are connected (1 in each pc room), only having a PC and printer connected on them.
I would appreciate any assistance.
Thanks in advance.
