Re: Deny client from obtaining IP address

I believe the only way you can configure a DHCP server to ignore
DHCPDISCOVER broadcasts is to setup restrictions by MAC address (which
can be spoofed). I do not see how you can restrict IP leasing via
Active Directory user authentication. You can restrict other network
resources until authentication has occurred via AD, but the client
system must already have an IP for this communciation to occur.
Meaning the DHCP server has already been solicited and assigned an IP.
Someone correct me if I am wrong

Thanks
Nathan

Hello all,

Is there a way that in DHCP or so, one can deny a client computer from
obtaining an IP address? We use Microsoft servers ADS environment and
I'd like to allow only those we want to obtain
an IP address. I don't want to make it too restricted where authorized
users are unable to connect. I'm sure there are some 3rd party apps that
can handle this and I welcome suggestions on those also. This is a
solution for denying connectivity to outsiders.

Thank you
