We have small network, all PCs are running WindowsXP Pro SP1.
One of the PC - let's name it "Main" have 2 NICs, and with simple ICS all other PCs can access Internet.
We use static IPs:
Main: 192.168.0.9/255.255.255.248;
Other PCs are using other 5 numbers in that network: 10, 11, 12, 13 and 14.
All is fine and works perfect!

But once there was a discuss:
Is it possible all other PCs haven't fixed IPs, but dynamic? Yes, I told, it's simple! - WinXP have builded internal DHCP server - it gives IPs from it's network address scope!
But when I was asked: Can every PC lease EXACTLY the same IP all the time - DHCP with static IPs? - I was shocked! I know, that DHCP in WinXP isn't possible to be tuned, as that one in Win98.

So, can this be realised: WinXP Pro SP1 to give via DHCP IP address to some PC depending only of it's MAC address?I know, that is possible with the help of extra software, like WinGate, or using server version of that OS, like Windows2000 Advanced Server, or Windows2003 Enterprice Server, for example. But the exact question is about WindowsXP Professional SP1 - can this OS be tuned with registry manipulation, so every PC lease exactly the same IP all the time, even after the lease period. And that IP is based on it's MAC address?

Thanks in advance! :hail:
