With the coming End of support in April, does anyone know how to prevent a Windows XP machine from getting on and accessing the network?
I know what machines on the network are currently Windows XP, so I could maybe do something with giving out incorrect DHCP parameters based on their MAC addresses, which would stop most people (machines), but that doesn't really solve for any unknowns (such as if someone were to bring in a home laptop that was running XP).
Looking for a solution that is centrally implemented and enforced and scales up easily.
DHCP: maybe not such a good idea:
Malicious users could always use a static IP address and then access the network.
You could allow only known MAC addresses and keep an internal database (or Excel sheet)
