Reading the MAC address of the client PC

[Greg Smith]

We are trying to limit application access to curtain PCs. We are
considering using the IP address, which I know how to get but the MAC
address would be ideal.

Is there a way to read the client's MAC address?
Any help is greatly appreciated.

You can't rely on the IP address, as it's so easy to spoof it...

but the MAC address would be ideal.

Not without some sort of client-side script / applet, and all the associated
security issues...

if its an internal lan and no proxies are used, you can ask the dhcp server
(or wins servers) and translate the ip to mac. if its an external lan, there
is no way without an active/x control that sent the mac address.
