  1. Opening the Microsoft Management Console
  2. Accessing the DHCP Service
  3. Set Server Scope Options
  4. Authorize & Activate the DHCP Scope
  5. Create A DHCP Scope
  6. Set Lease Duration

Opening the Microsoft Management Console (MMC)

  1. On the Windows server right click on "My Computer" and select "Manage"

Accessing the DHCP Service

  1. Select "Services and Applications" in the MIcrosoft Management Console (MMC)
  2. Select the DHCP service

Configure Scope Options (Server-wide)
This is where all global scope options are set for scopes served by this DHCP server. If you configure more than one scope on a server, you will need to set the scope options specific to each scope individually on the .

  1. In the MMC under DHCP will be a folder named "Server Options"
  2. Right click on the "Server Options" and select "Configure Options"
  3. This sets the default server options for all scopes created on this server including:
    1. General Tab
      Under this tab is a list of DHCP values that will be sent to all clients which connect to the network and attempt to use DHCP to aquire an IP address.

      Time Offset
      This sets the offset from the UCT time zone in Greenwich, UK. This allows a host to calculate which time zone it is in from DHCP alone.
      Router
      This setting is required if you have more than 1 subnet and/or need to reach the Internet. This is the default gateway. It is a list of all routers listed in the order they should be used. Windows hosts will try the first host, if it is unavailable, it will switch to the second after 45 seconds. Note that this only works properly in Windows 2000 and later, and not all non-Windows systems support this option.
      Time Server
      This is a list of the IP addresses of Windows Time servers on the network listed in order of preference.
      Name Servers
       
      DNS Servers
      List of servers performing Domain Name Service for the hosts in this scope.
      Log Servers
      Log servers act as a central location to forward all logging information to. This can be useful for tracking network wide errors and spotting patterns such as intrusion or tampering.
      Cookie Servers
       
      Coffee Servers
      Just kidding. This is no such setting, but there should be, considering there ARE cookie servers!!
      LPR Servers
      This is a list of IP's to which which a Unix print request may be sent.
      Impress Servers
       
      Resource Location Servers
       
      Host Name
      Name of the local host
      Merit Dump File
      This is a legacy function used mostly by computers belonging to the obsolete Merit Network. It states where on the filesystem to place a crash dump file.
      DNS Domain Name
      This is the DNS domain name which contains the hosts in this DHCP scope. Example: corporation.com.
      Swap Server
       
      Root Path
      Extensions Path
      IP Layer Forwarding
       
      Nonlocal Source Routing
       
      Policy Filter Masks
       
      Maximum DG Reassembly Size
       
      Default Time To Live
      How long packets are allowed to live on the network.
      Path MTU Aging Timeout
       
      Path MTU Plateu Table
       
      MTU Option
      Sets the Maximum Transmission Unit size. MTU defines the maximum size of a packet of data on the network.
      All Subnets Local
      This causes Microsoft computers to treat all hosts as being part of the local network.
      Broadcast Address
      The address in the network protocol used to contact all hosts. The address must be a broadcast address in thenetwork layer protocol.
      Perform Mask Discovery
      This causes the host to decipher/calculate the appropriate mask for the network.
      Mask Supplier Option
       
      Perform Router Discovery
      This instructs the DHCP client to learn the address of more than one default gateway. This allows the host to decide which default gateway is still reachable and will automatically reroute the data to the other default gateway if the first one fails.
      Router Solicitation Address
       
      Static Route Option
       
      Trailer Encapsulation
       
      ARP Cache Timeout
      This option defines how long a MAC address entry remains in the DHCP client's ARP cache.
      Ethernet Encapsulation
       
      TCP Default Time-to-Live
      Default time to live for all TCP connections (this is not measured in seconds, it is measured in hops).
      Keepalive Interval
      The interval between transmission of keepalive packets in protocols requiring keepalive messages.
      Keepalive Garbage
       
      NIS Domain Name

      A list of all the Unix NIS servers.
      NTP Servers
      This is a list of Network Time Protocol servers listed in the order of preference
      Vendor Specific Information
      This is a little oddball option made available for various products. This allows a network administrator to set a value to be read by some third party application that isn't currently supported.
      WINS/NBNS Servers
      This is a list of Windows Internet Name Server (WINS) servers. This should not be confused with Domain Name Service servers. WINS provides name-resolution for WINDOWS computers ONLY.
      NetBIOS over TCP/IP NBDD
       
      WINS/NBT Node Type
      This sets the NetBIOS Broadcast Type. Hosts should typically use the Hybrid setting as this is more efficient and less wasteful of network bandwidth. Possible values are:
      NetBIOS Scope ID
      If running NetBIOS, this sets the Scope ID (note that NetBIOS is still not a routable protocol).
      X Window System Font
      Default font for DHCP clients to use with X-11/X-motif
      X Window System Display
       
      NIS+ Domain Name
      The NIS+ domain hosts belong to. Microsoft hosts do not support NIS+ without the installation of third party software.
      NIS+ Servers
      A list of the Unix NIS+ servers.
      Boot Server Host Name
      The host containing bootstrap information. This is used primarilly in modern networks to enable functions such as Solaris' Jumpstart.

      Name of the default boot file on the bootstrap server for that DHCP client.
