Go to the Server Manager console window. You can get to this in various ways, In the IPv4 WINS settings step, click Next. Again, we haven’t set this up yet.

Working with Networking Services | 131 j. Add a DHCP scope by clicking the Add button. A scope is a range of IP addresses that can be handed out to clients. Add the following information: • Scope name: Proseware Scope1 • Starting IP address: 192.168.1.150 • Ending IP address: 192.168.1.199 • Subnet mask: 255.255.255.0 • Default gateway: 192.168.1.1 • Subnet type: Wired An example of this is shown in Figure 6-1. Of course, this information will vary depending on the confi guration you want for your network. Also, you have the option to select wireless as the Subnet type. Note that Wired has a lease duration of six days by default, whereas Wireless has a duration of eight hours. Wireless connections should always have a shorter lease equal to the duration of one work day or less. Make sure that “Activate this scope” is checkmarked and click OK. That adds the scope to the list. You can add more in the future if you wish, but for now, we will leave it as is. Click Next to continue.

k. In the Confi gure DHCPv6 Stateless Mode window, select Disable. We are focusing

on IPv4 for this exercise, but IPv6 could always be confi gured later if neces- sary. Click Next.

l. For the IPv6 DNS Settings window, simply click Next. We will not be

confi guring this feature.

m. You should now see a Confi rmation window Figure 6-2. Review the information

in this window and make sure it is correct before clicking Install. In the fi gure, we left DHCPv6 Stateless Mode enabled because our particular server needs to have it running. Figure 6-1 Adding a DHCP scope 132 | Lesson 6 When complete, the Results should show that the installation succeeded. Click Close to fi nish. This will authorize the server. At this point, the DHCP server is ready to hand out IP addresses to client computers.

3. Go to a Windows client computer and obtain an IP address automatically:

a. Access the IPv4 Properties dialog box for the wired network adapter.

b. Select the Obtain an IP address automatically radio button.

c. Click OK for all dialog boxes.

d. Open the command prompt and type ipconfi g all. You should obtain an

IP address automatically from the list of IP addresses in the DHCP server’s IP scope. Most likely, it will be the fi rst one on the list: 192.168.1.150.

e. If, for some reason, you cannot obtain an IP address, check your confi gura-

tion settings on the server. Also, on the client, you can attempt an ipconfi g release and ipconfi g renew to retry obtaining an IP address. In some cases, you might obtain an IP address from another DHCP device or server. If this is the case, remove that device from the network. If your client has obtained an address on the 169.254.0.0 network, then APIPA has intervened and self- assigned an IP address. See the next exercise for information about how to dis- able APIPA.

f. Test your new IP address by pinging the IP address of the DHCP server and

another client on the network. Disable any fi rewalls that might block pings.

4. When you are finished, return the client computers to normal. If necessary, access the

server and stop the DHCP service. Figure 6-2 DHCP Confirmation window
