The short answer is you can't do what you want to do with 1 or 2 NICs.

I count a total of three separate static and three separate dynamic IP addresses.

On a single NIC, you can set it up for either a static IP or a dynamic one, but not both.
A single NIC can only have a single static IP address assigned. One possibility is that with WinXP PRO you can enter information for an alternate network. Theoretically, you could set it up with 1 static and 1 dynamic, or 2 static IP addresses.You can't really set it for 2 dynamic IP addresses (you don't really need to) for the reasons stated below

Addresses assigned by DHCP: This is totally dependant upon the network to which you are physically connected. Windows will take a DHCP assigned IP address from the first DHCP server it hears. If you physically connect the computer to a different network, it will accept an IP address from the DHCP server on that network.

You can set up a server with more than 1 NIC, but you still have the problem of either static or dynamic, but not both.

It is a bad idea to give a server a dynamically assigned IP address, since the potential for IP addresses changing could cause loss of connectivity for anyone needing to connect to that server.

There is third-party software available (like Netswitcher - www.netswitcher.com) that will allow you to enter settings for access to multiple networks. Hoewever, only one set of settings is active at any one time.

Hope this helps.

In Windows 9x, you could install multiple instances of the TCP/IP stack and configure each one differently. I have not seen this capability in the NT-based OSes - these use only a single instance of the TCP/IP stack which can be configured as either dynamic or static. Regarding Tim's statement that "A single NIC can only have a single static IP address assigned," this is simply not true. In the NT-based OSes, you can assign hundreds (I do not know what the upper limit is, but it is over 500)of static IP addresses to a single NIC.

you can set more than one ip in professional also but at the same time you can not set dhcp ip to be alloted automatically to the client, if u selected this option you can't have remaining. if you selected a static ip then u can add other ip addresses also go in properties of nic and go in advanced there you can add static ip addresses.
