The DHCP Server found in Windows 2000 responds to requests from both DHCP clients and BOOTP clients. Although the two protocols are similar, they differ in the way they initialize. (See Chapter 2 for more information on BOOTP.)
Besides requesting IP address information (IP address, subnet mask, default gateway), BOOTP clients can request the location of a boot image file. The file is located on a Trivial File Transfer Protocol (TFTP) server. The BOOTP client uses the boot image file to complete its initialization.
Windows 2000 DHCP Server supports BOOTP clients by providing dynamic IP address allocation as well as providing boot file information.
Dynamic IP address allocation is provided by configuring a BOOTP address pool within a DHCP scope on the server. This is covered in detail in Chapter 5 .
Setting up the DHCP server to provide boot file information requires two steps:
For each BOOTP client, add a client reservation within an active DHCP scope. (see Chapter 5).
In the BOOTP table, add BOOTP entries for each BOOTP client’s operating system and hardware platform.
