BOOTP clients that do not specify the DHCP option code 55 (the Options Request List parameter) can still retrieve the following options from DHCP servers running Windows NT Server 4.0 or later. Table 4.11 lists the DHCP options available for BOOTP clients.
Table 4.11 DHCP Options for BOOTP Clients
| Code | Description |
|---|---|
| 1 | Subnet Mask |
| 3 | Router |
| 4 | Time Server |
| 5 | Name Server |
| 9 | LPR Server |
| 12 | Computer Name |
| 15 | Domain Name |
| 17 | Root Path |
| 42 | NTP Servers |
| 44 | WINS Server |
| 45 | NetBIOS over TCP/IP Datagram Distribution Server |
| 46 | NetBIOS over TCP/IP Node Type |
| 47 | NetBIOS over TCP/IP Scope |
| 48 | X Window System Font Server |
| 49 | X Window System Display Manager |
| 69 | SMTP Server |

In order to obtain other options, the client must specify option 55 in the BOOTP request. Windows 2000 DHCP servers return the options in the order listed above and return as many options as can fit in a single datagram response.
Important
When configuring client reservations for use with BOOTP clients, remember that DHCP options can apply equally to DHCP and BOOTP clients. Therefore, it is imperative that you correctly configure your scopes.
