Computer Names and IP Addresses

Before you begin, determine and verify the computer names and IP addresses of all the computers on which you will be installing Connection Point Services..

To determine and verify the computer name

In Control Panel, double-click Network.
Click the Identification tab. The computer name should appear in the dialog box.

To determine and verify the IP address

On the Start menu, point to Programs, and then click Command Prompt. A Command Prompt window appears.
At the command prompt, type IPConfig.

Verifying IP Connectivity By Using the PING Utility

The PING utility is useful in testing IP connectivity and Domain Name Server (DNS) entries. The following example shows how to check the DNS entry as well as connectivity between the administration tool computer and the Connection Point server by "pinging" the server name from the computer on which you have installed the administration tool. For more PING command instructions or for more suggestions on what to do if the test fails, see Windows NT Networking Supplement Version 4.0.

To ping a computer by computer name

At the command prompt, type the following, where computer name is the name you have assigned to the computer:
```
ping computer_name
```

The following is sample output from the command:

C:\>ping computer_name

Pinging computer_name [138.57.7.27] with 32 bytes of data:

If Ping by Computer Name Fails

If you have completed a successful ping by IP address, but a ping by computer name fails, it is likely that the DNS has not been properly configured. In this case, check your DNS settings. (To check DNS settings, open the Network utility in Control Panel, double-click TCP/IP, and then click the DNS tab.) If you are running Windows NT Server 4.0 on your DNS server, you can find information about DNS in the Windows NT Server documentation.

If the ping by computer name fails to confirm a correct DNS entry, you can ping by IP address to test for network connectivity and platform functionality.

To ping a computer by IP address

At the command prompt, type the following, where IP_address is the IP address you haveassigned to the computer:
```
ping IP_address
```

If Ping by IP Address Fails

If the ping by IP address fails, the administration tool computer and the Connection Point server are not properly networked. Examine the network card and network cables to be sure that each computer is properly connected to the network. Check to be sure that TCP/IP drivers are loaded.
