Configuring TCP/IP on Windows 2000

TCP/IP is the default network protocol in Windows 2000. This guide covers static IP configuration, DNS settings, and common troubleshooting commands.

Setting a Static IP Address

1. Open Control Panel → Network and Dial-up Connections.
2. Right-click Local Area Connection and select Properties.
3. Select Internet Protocol (TCP/IP) and click Properties.
4. Select Use the following IP address and enter:
   • IP address: e.g., 192.168.1.10
   • Subnet mask: e.g., 255.255.255.0
   • Default gateway: e.g., 192.168.1.1
5. Under DNS server addresses, enter your primary and secondary DNS servers.
6. Click OK twice to apply the settings.

Useful Command-Line Tools

REM Display IP configuration

DNS Client Configuration

For domain-joined computers, the preferred DNS server should be the domain controller running DNS. Set the ISP DNS server as the alternate. This ensures Active Directory SRV records are resolved correctly.

WINS Configuration

WINS (Windows Internet Name Service) resolves NetBIOS names to IP addresses. Configure WINS on the WINS tab of the TCP/IP properties dialog. In a pure Windows 2000 or later environment, WINS is optional if all applications use DNS.
