How to restrict internet access on a remote host?

Question

Computer networks

The essence of the question is this:
Software is installed on a remote host (access via RDP), perhaps not one, but some number N. How to disable the network on this host, but still be able to use it? The virtualization tool in this case is vmware ESXi
Thanks

Answer 1

Manage the machine not through RDP, but through virtualization tools.
RDP is a network protocol. No network - no protocol.
Answer to the corrected question:
You can specify fake DNS, which will not allow any software to get the address of the desired host. And you can connect just like before.
PS Do not forget to flushdns after installing DNS.

Answer 2

you can hack and cut off all communication with ports through the firewall, acre of the rdp port, well, plus a filter to a remote address.
most programs will not see the network.
depending on what is meant by the lack of a network.
