Blocking private network shares

[GJMohrJr]

I have 2 computers, both running windows10, connected to same private network. 

Computer 1 is running Kaspersky Internet Security. Computer 2 is running MS Defender. 

Computer 1 can access the shares on Computer 2 no problem.

But Computer 2 cannot access the shares on Computer 1. Get error message “Windows cannot access \\Computer1 ….”

If I pause Kaspersky protection on Computer 1, then Computer 2 CAN access the shares or Computer 1. 

What / How do I change in Kaspersky Internet Security to allow Computer 2 to access Computer 1 without having to pause protection??

@GJMohrJrWelcome.

Please try this :

Kaspersky > Settings > Protection > Firewall > Configure packet rules
=> Local services (TCP) > Rightclick > Edit > Action : "Allow" > Save
=> Local services (UDP) > Rightclick > Edit > Action : "Allow" > Save
=> Reboot 

Also :
> Settings > Protection > Firewall > NetWorks :
Please check if Your Home Network adapter is set as Trusted or Local.
