How do I assign a host name and IP address to my Windows NT 4.0 system?
Go to Start->Settings->Control Panel. Double click on the “Networking” icon. You can check and set your Computer Name (host name) in the “Identification” tab. You can also set your workgroup here (it is useful to assign related computers on the network to the same workgroup, so you can see them in Windows Explorer). To set the IP address and related settings, go to the “Protocols” tab. Select TCP/IP, and go into “Properties” (if TCP/IP is not listed, you will need to add this protocol; you will need your NT 4.0 installation disk to do this). Under TCP/IP Properties, you can assign an IP address, a subnet mask (usually 255.255.255.0), and a default gateway (blank unless you have an outside internet connection). You can also define a Domain Name Server here (for accessing external web sites). If you are on a large network, your system administrator should be able to tell you what these settings should be.
