can you please explain in more detail what you're trying to do?

mac addresses are only unknown for a few seconds, then they become known and stored in each devices ARP table.

maybe you mean ip addresses?  

what kind of communication do you want to block?  from what to what, by what protocol

I want to block all communication with network.

you could disable dhcp, and assign an ip address to the machines you want on the network... that way when someone plugs in a different machine, they get no ip address... is that what you mean?

or, you could get a network switch which provides for VLAN functionality, and put your stuff in one vlan, that will block communication from anything not specifically allowed in the vlan

windows itself can do little with mac addresses... you can tell your dhcp server "always give [this ip address] to [this mac address]" but that's basically the extent of it.

basically yes, but users can assign IP address manuallly.
I am not sure if all my switches support MAC filtering or VLANs.

Is there any other way how to block unwanted PCs?

you can use the windows firewalls on the machine(s) to allow only specific ip addresses - but no not mac addresses

you would need an expensive network switch to specify things by mac address/port numbers/vlans

blocking in your case might be best done at the application level, via windows firewalls and passwords
