Configuring the Network Protocols in Windows 95 and Windows NT

You usually configure the network protocols as part of the Windows 95/NT installation procedure. If you changed networks or network properties, or if you did not set up the network during the installation process, you will need to configure TCP/IP (Transmission Control Protocol/Internet Protocol) to connect to your network. Refer to the documentation that came with your version of Windows 95/NT.

To diagnose problems with your network, refer to Appendix A, Troubleshooting.

Setting TCP/IP Properties

Before you can configure TCP/IP, you will need to obtain certain information from the network administrator at your site. Make sure you have the following information before you begin:

Your SunPCi computer name (the one you entered when you installed Windows 95/NT). This name also appears on the Identification tab of the Network Control Panel. (The Network Control Panel is explained in the following procedure.)

The IP address for your SunPCi computer (must be different from your workstation's IP address).

The subnet mask for your site's network.

The IP address for your router/gateway (if used).

The host name, domain name, and IP address for each DNS (Domain Name Service) server at your site (if used).

To configure TCP/IP, use the Network Control Panel in Windows 95/NT. Enter the information you obtained in this list in the corresponding fields. For more information on setting up networking with Windows 95 or Windows NT, refer to the documentation that came with your version of Windows.

Networking Your Workstation and SunPCi Host

By default, your workstation and SunPCi host do not see each other on the network. If they need to communicate using the network, you will need to send the information through your network router. To configure your workstation and SunPCi system, you will need to know the IP addresses of your workstation, your SunPCi card, and the network router. In addition, you need the netmask used on your network. If you do not know the IP addresses or do not yet have one assigned to SunPCi, see your network manager.

Note –

This procedure will not work if you are using DHCP to obtain IP addresses for either your workstation or for SunPCi.

In this example, the systems have the following

SunPCi card IP address: 192.9.200.1

Host workstation IP address: 192.9.200.2

Router IP address: 192.9.200.3

Subnet mask: 255.255.255.0

Before you start, make sure you have account access to the system you are using as a network router.

To set up the connections between the systems, perform the following steps:

In Windows 95/NT, select the Start button, then choose Programs and MS-DOS Prompt from the menus.

Type the following command at the DOS prompt (do not type the C:\> prompt):
```
C:\> cd windows
```

If you want networking to take place every time you start up Windows 95 or Windows NT, you will need to create a batch file to add to your Windows Startup folder (for example, C:\WINDOWS\Start Menu\Programs\Startup\ADDROUTE.BAT). The file would contain two lines similar to the following (substituting the IP addresses for your systems). For example:
```
@echo off
route add 192.9.200.2 mask 255.255.255.0 192.9.200.3
```

On the host workstation, type the following command, substituting the IP addresses of your SunPCi card and router (proxy system) for the ones used in the example:
```
% route add 192.9.200.1 192.9.200.3 1
```
If desired, you can enter this information into an /etc/rc script that will run each time you reboot your workstation.

On the router (which can be another workstation, a router, or another computer on the same subnet as your workstation and SunPCi host), type the following command, substituting the IP addresses of your SunPCi card and your workstation for the ones used in the example:
```
% route add 192.9.200.1 192.9.200.3 0
% route add 192.9.200.2 192.9.200.3 0
```

You should now be able to ping the SunPCi host from the workstation and the workstation from the SunPCi host. Refer to Networking Problems for more information on troubleshooting TCP/IP connections.

Using PC Launcher With SunPCi Software

Once you have configured your workstation and network to communicate using TCP/IP, you can use PC Launcher software to launch SunPCi from your Solaris desktop. PC Launcher is a CDE utility; it is not available for OpenWindows.

Before PC Launcher will work with SunPCi, you need to enter name server information in the TCP/IP settings in the Network Control Panel. Refer to Setting TCP/IP Properties for more information on how to enter name server (DNS) information. Consult your network manager to make sure that your workstation also contains the correct name server information.

Note –

Make sure that the SunPCi host and your workstation can ping each other by name, not just by IP address. PC Launcher needs to identify both hosts by name before it will work.
