I have 2 computers with Win 10 in a small business runing in my home. I have a program or aplicaction running in Computer 1 and we are connected to the same private network and I have access to that program from Computer 2.  In order to access and run the program in Computer 1 from Computer 2, I have to disable Kaspersky Internet Security in Computer 1 and everything work fine, When I enable Kaspersky Internet Security in Computer 1, from Computer 2 I CANNOT access the program in computer 1. What can I do with the configuration of KIS in computer 1.
