Other Tools

You can use a number of tools to help troubleshoot and isolate the source of TCP/IP problems. Each tool gives you a different view of the process used to resolve an IP address to a hardware address, and then routes the IP packet to the appropriate destination.

ARP. ARP (Address Resolution Protocol) can be used to see the entries in the Address Resolution table, which maps network card addresses (MAC addresses) to IP addresses. You can check to see whether the IP addresses you believe should be in the table are there and whether they are mapped to the computers they should be. Usually, you do not know the MAC addresses of the hosts on your network. However, if you cannot contact a host, or if a connection is made to an unexpected host, you can check this table with the ARP command to begin isolating which host is actually assigned an IP address.
ROUTE. ROUTE is a command-line utility that enables you to see the local routing table and add entries to it. Execute the ROUTE PRINT command to see the contents of the route table. Execute the ROUTE ADD command to add entries to the route table, and make these entries permanent with the -p switch. Execute the ROUTE DELETE command to remove entries from the route table. Execute the ROUTE command without any switches to see a help file describing all the switches for the command.
NBTSTAT. NBTSTAT is a command-line utility that enables you to check the resolution of NetBIOS names to TCP/IP addresses. With NBTSTAT, you can check the status of current NetBIOS sessions. You can also add entries to the NetBIOS name cache from the LMHOSTS file or check your registered NetBIOS name and the NetBIOS scope assigned to your computer, if any. Execute NBTSTAT -c to display the contents of the NetBIOS name cache. Execute NBTSTAT -R to empty the NetBIOS name cache and reload it from the LMHOSTS file. Execute NBTSTAT -S to display the current NetBIOS sessions with their status. Execute NBTSTAT /? for a complete description of the NBTSTAT command options.
NETSTAT. NETSTAT is a command-line utility that enables you to check the status of current IP connections. Executing NETSTAT without switches displays protocol statistics and current TCP/IP connections. Executing NETSTAT with the -a switch (NETSTAT -a) displays all connections and listening ports, even those ports not currently involved with a connection. NETSTAT -r displays the route table along with active connections. Execute NETSTAT /? for a full description of the NETSTAT command options.
TRACERT. TRACERT is a command-line utility that enables you to verify the route to a remote host. Execute TRACERT hostname, where hostname is the computer name or IP address of the computer whose route you want to trace. TRACERT will return the different IP addresses the packet was routed through to reach the final destination. The results also include the number of hops needed to reach the destination. Execute TRACERT without any options to see a help file that describes all the TRACERT switches.
NSLOOKUP. NSLOOKUP is a command-line utility that enables you to verify entries on a DNS server. You can use NSLOOKUP in two modes: interactive and non-interactive. In interactive mode, you start a session with the DNS server in which you can make several requests. In non-interactive mode, you specify a command that makes a single query of the DNS server. If you want to make another query, you must type another non-interactive command. NSLOOKUP is described more completely in Chapter 12, “Domain Name System.”
SNMP. The SNMP protocol enables TCP/IP to export information to troubleshooting tools like Performance Monitor or other third-party tools. By itself, SNMP does not report any troubleshooting information. If you are using tools that depend on SNMP, however, you cannot see all the information available from these tools until you install SNMP. To install SNMP, open Control Panel, Network, and then add SNMP from the Services tab.
Performance Monitor. Performance Monitor is a Windows tool you can use to monitor TCP/IP performance on the local computer and also on the local network segment. Performance Monitor is included in the Administrative Tools menu on any Windows NT computer. You must also install SNMP to see more complete troubleshooting information for the TCP/IP protocol.
Network Monitor. Network Monitor is a Windows tool that enables you to see network traffic that is sent or received by a Windows NT computer. Network Monitor is included with Windows NT 4.0. To install Network Monitor, open Control Panel, Network, and then add the Network Monitor Tools and Agent from the Services tab. The version of Network Monitor that comes with Windows NT 4.0 is a simple version; it only captures traffic for the local machines (incoming and outgoing traffic). Microsoft’s System Management Server, a network management product, comes with a more complete version of Network Monitor that enables you to capture packets on the local machine for the entire local network segment. You can also filter out traffic that isn’t important to the troubleshooting process.
