Performing Post-Installation Tasks
Tip Cisco strongly recommends that you configure a static IP address instead of using DHCP. For more
information on DHCP and static IP addresses, see the “What data must I provide to configure the
server?” section on page 9.
Step 3 To configure static IP information, click Use the following IP address; in the appropriate fields, enter
the server IP address, subnet mask, and default gateway, as described in the “What data must I provide
to configure the server?” section on page 9.
Step 4 To use DHCP, click Obtain the IP address automatically.
Caution You must have a name resolution method in place. If you do not plan to use DNS, you must configure
WINS or configure local name resolution by updating the LMHOSTS file with IP address and hostname
information for every server in your cluster.
If you do not plan to configure DNS, leave the DNS fields empty in the Internet Protocol (TCP/IP)
Properties window. Make sure that the radio button, Use the following DNS server addresses, is not
chosen, so you can configure WINS or local name resolution; to configure WINS, see Step 6. To
configure LMHOSTS file, see Step 7.
To Configure DNS
Step 5 In the Internet Protocol (TCP/IP) Properties window, click the Use the following DNS server addresses
radio button; then, enter the IP addresses of the primary and alternate DNS servers. Click OK.
To Configure WINS
Step 6 To configure WINS, perform the following procedure:
a. In the Internet Protocol (TCP/IP) Properties window, click the Advanced button.
b. Click the WINS tab.
c. Click the Add button.
d. Enter the WINS server address.
e. Click Add.
f. To add additional server addresses, repeat Step 6.
g. After you complete Step 6 for all addresses that you want to add, click OK.
To Update the LMHOSTS File
Step 7 If you did not configure DNS or WINS server information, and if you are installing multiple servers in
a cluster, you must configure local name resolution by updating the LMHOSTS file, so it contains a
mapping of the IP address and hostname of each server in the cluster. To update the LMHOSTS file,
perform the following steps:
a. On the server that runs this operating system, choose Start > Run.
b. In the Open field, enter command; click OK.
c. At the DOS prompt, enter notepad c:\winnt\system32\drivers\etc\hosts.
The file opens.
