Troubleshooting TCP/IP<br />
Use Table 11.18, in addition to the TCP/IP information presented<br />
earlier, to troubleshoot a TCP/IP connection on either a LAN or<br />
dial-up connection.<br />
Windows 2000 uses a single networking wizard to configure both<br />
types of network connections. With other versions of Windows,<br />
TCP/IP configuration for LANs takes place in the Network icon in<br />
Control Panel, whereas modems are configured through the Dial-<br />
Up Networking properties sheet for a given dial-up connection.<br />
Web browsers that communicate through proxy servers or gateways<br />
with the Internet also might require special configuration options.<br />
Use the Internet icon in Control Panel to adjust Microsoft Internet<br />
Explorer TCP/IP settings. With Netscape Navigator/Communicator,<br />
use Edit, Preferences, Advanced, Proxies to adjust proxy server settings.<br />
