Set Up Networking Software for an
Ethernet Connection in Windows NT

How To...

1. Set Up Your Ethernet Card
2. Install and Configure TCP/IP

Getting Your Network Information

In order to use the Cornell network via an Ethernet connection, you will need to contact your network administrator to obtain:

• an IP address
  
• the subnet mask address
  
• the default gateway address
  

Set Up Your Ethernet Card

» If you installed your Ethernet interface before (or at the same time as) you installed Windows NT, then the system should have automatically detected it and you should proceed to the next section, Install and Configure TCP/IP. Optionally, you may follow steps 1-3 below to confirm that your interface is recognized.

Important: If your Ethernet interface is a non-PCI card, you may need to contact the HelpDesk, or check the manufacturer's documentation for further help. If you're buying an Ethernet card, see Ethernet Recommendations.

» If you obtained an Ethernet interface after Windows NT was already on your computer, then do the following:

1. From the Start menu, select Settings and then select Control Panel.
2. Double-click on the Network icon.
3. Click on the tab labeled Adapters. You should then see an entry for your Ethernet card. If you do not see one, continue to step 4 to install it. Otherwise, click OK and skip ahead to Install and Configure TCP/IP.
4. Click Add... and follow the on-screen instructions. Select your Ethernet card from the list shown, or, if it is not included in the list, click Have Disk... and insert the diskette that came with the card. Even if your card does appear in the list, it's a good idea to use the diskette to make sure you have the latest drivers.
5. Restart your computer if Windows gives you the option to do so. Wait for the system to restart before continuing with the next section.

Install and Configure TCP/IP

1. From the Start menu, select Settings and then Control Panel.
2. Double-click on the Network icon, then click the Protocols tab.
3. In the list of Network Protocols, look for TCP/IP Protocol. If you don't see it, click Add..., select TCP/IP Protocol, and then click OK.
4. Select TCP/IP Protocol in the list of Network Protocols and then click Properties... A Microsoft TCP/IP Properties window will open.
   
   
   
   
   
5. Click on the IP Address tab if it is not already selected.
   1. Make sure that the radio button next to Specify an IP address is selected.
   2. Enter your IP Address, Subnet Mask, and Gateway Address (in the Default Gateway box) given to you by your Network Administrator.
      
      
   
   
   
6. Click on the DNS tab.
   1. In the Host Name and Domain fields, enter the Host Name and Domain given to you by your Network Administrator.
   2. In the box under DNS Service Search Order, look for the following numbers:
      132.236.56.250
      128.253.180.2
      192.35.82.50
      If these numbers are already present, skip ahead to step 6c. If not, click Add... below the box labeled DNS Service Search Order. A TCP/IP DNS Server dialog box will open. Enter 132.236.56.250 and click Add. Repeat these steps for the next two numbers.
   3. Click Add... below the box labeled Domain Suffix Search Order. A TCP/IP Domain Suffix dialog box will open. Enter cit.cornell.edu and click Add.
   4. Click OK to close the Microsoft TCP/IP Properties window.
      
      
   
   
   
7. In the Network control panel, click on the Identification tab.
   
   
   
   
   
8. Click Change... An Identification Changes window will open.
   1. In the Computer Name box, enter the Host Name given to you by your Network Administrator. Click OK. You will see a message that your computer's name has been successfully changed. Click OK.
   2. In the Network control panel, click Change... again. In the Workgroup box, enter the Workgroup name given to you by your Network Administrator. Click OK. You will see a welcome message. Click OK.
      
      
   
   
   
9. Click Close to close the Network control panel.
10. Restart your computer.
11. You should now be able to access network-based services.
