.SYNOPSIS
|
|
Sets network profile to Private, enables ping, and enables Network Discovery.
|
|
|
|
.DESCRIPTION
|
|
Sets all connected network adapter profiles from Public to Private. Private
|
|
profile enables file sharing, network discovery, and other LAN features.
|
|
Enables ICMP echo (ping) via Windows Firewall for diagnostic purposes.
|
|
Enables the Network Discovery firewall rule group for the Private profile
|
|
so this PC is visible to other computers on the local network.
|
|
|
|
.ITEMS
|
|
nastavit-sitovy-profil-private: Sets all connected network profiles to Private via Set-NetConnectionProfile. Public profile blocks most LAN features. Private is required for file sharing, printer sharing, and network discovery. Applied to all currently connected adapters.
|
|
povolit-ping-icmp-firewall: Enables "File and Printer Sharing (Echo Request)" firewall rules for ICMPv4 and ICMPv6. ICMP echo is disabled by default on clean Windows. Required for network diagnostics, monitoring tools, and basic connectivity verification.
|
|
zapnout-network-discovery: Enables the Network Discovery firewall rule group (FPS-NB_Name-In-UDP, LLMNR, etc.) for Private and Domain profiles via Set-NetFirewallRule. Allows this PC to appear in Network Neighborhood and browse other machines.
