          How do I set up my Microsoft Windows PC to get a dynamically
          assigned IP address from a SCO Unix server using DHCP (Dynamic
          Host Configuration Protocol)?

          The following example shows how to set this up. In this example,
          only one IP address is set up as available to a single client. In
          practice, usually a set of IP addresses or pools are assigned. A
          Windows 95 client is used but it is similar for Windows 98.

          (1) First, the SCO Unix DHCP server is set up:

               Start the SCOadmin interface, choose "Networking", "DHCP
               Server Manager", "Edit", "Add", and then add a subnet entry

               Set the subnet, in this case the Network address of the IP
               address we are going to use, 123.456.789.0

               Set the Mask, that is, 255.255.255.0

               Set the pool name, in this case "scotest"
               (which you will create shortly)

               Set the "Description" of this pool for easy identification

          Then work down to the next line of options and across and into each
          one:

                Make the Lease "unlimited"

                Choose "Generic"

          In the example network, a hardware router was available:

                Subnet Generic options configuration

                From the pick list, choose "3 - routers" and Add

                Assign the IP address of, for example, "123.456.789.5"

                Add this to the "Array contents" and click "OK" to finish

          Now click on "Address Pools" and you are placed inside the Address
          Allocation Manager (AAS). Choose "Add" and add the pool "scotest"
          and the IP address you will use for the client to it, in this case,
          "123.456.789.11"

          Click "OK" when finished. Then choose "Host" and "Return to DHCP
          Server Manager".

          Finally, you will come back to the initial menu. Choose "OK".

          (2) Configure the Windows system:

               Choose "Start", "Settings", "Control Panel", "Network",
               "Configuration", and highlight the "TCP/IP" network component

               Click on "Properties", then choose "IP Address" and toggle the
               check box to the setting "Obtain an IP address automatically"

               Also, within "WINS Configuration", enable the "Use DHCP for
               WINS Resolution" option at the bottom of the page

               DNS is enabled on the client in the "DNS Configuration" option
               with "Enable DNS" on and the "Host" set to the name of the
               immediate DNS server. The domain name is set to, for example,
               "test.sco.com".

          On reboot of both systems, the Windows PC client should collect its
          IP address from the server. If not a message similar to this will
          appear:

               ..could not obtain IP address from DHCP server

          If it has obtained the address, you should be able to ping out to
          other sites or telnet from the MS-DOS prompt window.

          You can see routing from the client with the "netstat" command:

               C:\WINDOWS>netstat -r

          The UnixWare 7 Address Allocation Manager with the Networking
          utilities inside SCOadmin should show the address that was set
          up on the server allocated to the client. Choose "View", "Address
          Allocation" and then double-click on the pool name being used. It
          should show something similar to:

               Pool Name       Type            Total           Used

               scotest         INET            1               1
               123.456.789.11  ALLOCATED DHCP  infinite 18:32  02/03/00

          Click on the line containing the IP address and the title changes
          to:

               Address         Status  Service Lease    Allocated      Released

               123.456.789.11  ALLOCATED DHCP  infinite 18:32 02/03/00
