Whether you’re designing, maintaining, or troubleshooting TCP/IP-powered networks, much is at stake. The slightest error or unplanned outage can bring an organization to a standstill. When TCP/IP networks fail, employees can’t access important network connections, including the Internet. Remote users are stopped in their tracks. E-mail fails. Files can’t be shared. In short, operations grind to a halt. Regardless of your organization’s size, you must ensure that its network is designed and subnet- ted properly, administered efficiently, and troubleshot quickly. TechRepublic has built a solution- packed book and CD tool kit to help you do just that. TechRepublic’s newly updated Administrator’s Guide to TCP/IP, Second Edition, and its accompany- ing CD-ROM tool kit, provides you with proven expertise, timesaving solutions, and helpful tips to build and keep enterprise TCP/IP networks running smoothly. Whether you have questions regard- ing TCP/IP fundamentals, DHCP, DNS, routing, cabling, or troubleshooting, you’ll find a wealth of solutions for all things TCP/IP. For example, TechRepublic’s Administrator’s Guide to TCP/IP, Second Edition will help you: X Master TCP/IP basics. X Subnet and supernet networks. X Implement efficient routing techniques. X Troubleshoot TCP/IP failures. X Configure NAT, WINS, DNS, DHCP, and other critical protocols. X Monitor and optimize your TCP/IP network. The TCP/IP CD-ROM tool kit included with the Administrator’s Guide to TCP/IP, Second Edition is packed with helpful tools to help ensure you have the checklists, forms, and scripts you need to diagnose and repair network failures quickly and efficiently. The CD-ROM also contains a special bonus chapter outlining critical Cisco solutions. Don’t attack network failures alone; turn to TechRepublic for expert, field-tested advice.
