I have 2 instances (windows machine) in the same security group.
I create a network drive on instance machine(A) for share a folder to other instance machine(B). But when I map a network path on machine(B), windows cannot find the path.
Here are my Security group setting:
ALL TCP Port 0-65535, Source 0.0.0.0/0 ALL UDP Port 0-65535, Source 0.0.0.0/0 RDP Port 3389 , Source 0.0.0.0/0
I tried turn off firewall, but still cannot link 2 computer together.
I am 0 knowledge on networking, so I don't know how to use other method to check my instance machine are connected together or not.
