Common Problems Problems NetTool Detects 6 Things to Consider Problems NetTool Detects You can think of problems fitting into one of two categories: link connectivity or network. Link connectivity problems relate to cabling or cabling properties while network problems involve PC/network configuration settings or PC-to-server interactions. This section lists by category the problems that NetTool can detect. For each problem, an explanation (if needed) is given and possible corrective steps are provided.
NetTool Users Manual • Problem: Pair mismatch • Explanation: The link pulse is being sourced on the same wire pair by both sides. This problem does not prevent connection to the network. NetTool automatically swaps the pairs to correct this problem. Remedy: Check the cabling. It may be plugged into an uplink port. Also, there may be a crossover cable between NetTool and the device. • Problem: Duplex mismatch Explanation: One side is running at half duplex and the other side is running at full duplex.
Common Problems Problems NetTool Detects Network Problems This section lists all of the network problems. Keep in mind that this is not an exhaustive list of troubleshooting steps. If you know what you need, the network administrator for the network you are troubleshooting can provide you with a lot of information to correct these problems. Health Problems • • 6 Problem: Excessive utilization seen (also collisions).
NetTool Users Manual NetWare • • Problem: Ethernet frame-type mismatches. Explanation: After a PC boots up, it sends a broadcast to initiate a connection with the closest server. If after three attempts there is no response, this problem is listed in the log. Explanation: For the PC and network to communicate, they both must be configured for the same frame type (802.3-raw, 802.2, Ethernet II, and SNAP). You can configure a client for a single frame type.
Common Problems Problems NetTool Detects TCP/IP • • Problem: PC using incorrect IP subnet mask. Remedy: Access PC network properties and correct the IP subnet mask. Remedy: Identify at least one of the devices and change its address to a valid one that is not being used. Problem: Router issued ICMP redirect. Hosts or devices using incorrect gateway/routers. Explanation: NetTool has determined that the PC is not properly configured. Remedy: Access PC network properties and correct the IP address.
NetTool Users Manual • Problem: DHCP server issuing IP address that causes duplicate IP on network. • Explanation: There are multiple DNS servers on the network and the PC is configured for the wrong one. Explanation: The DHCP server in question is not detecting an address and is provisioning a duplicate. Remedy: This problem can be caused by a statically configured PC. Find the statically configured PC on the network and changes its IP address to a valid and unique IP address.
Common Problems Problems NetTool Detects • Problem: No WINS server found on network to resolve names. NetBIOS • Explanation: The PC is configured to use WINS (Windows Internet Name Service) and none can be found. Remedy: Determine what domain names and privileges are required and correct the PC’s configuration. Problem: PC WINS incorrect. Explanation: NetTool sees a WINS server on the network but it is not the one configured on the PC in question.
NetTool Users Manual • Problem: xxx.xxx.xxx.xxx causing duplicate NetBIOS name. Email • Explanation: Only one unique NetBIOS name is allowed on a domain. Explanation: The Simple Mail Transfer Protocol (SMTP) server information is either not configured or is not correctly configured on the PC. The server itself may be down as well. Remedy: The name specified on the PC needs to be changed to eliminate duplication.
Common Problems Problems NetTool Detects • Problem: Unable to connect to POP3 server Explanation: The PC cannot find the POP3 server it is configured to find. The server itself may be down as well. Printer • Remedy: Access NetTool’s Key Devices list to view a list of IP printers and correct the problem in the printer setup area on the PC. Problem: Unable to connect to IMAP server Explanation: The PC cannot find the IMAP server it is configured to find. The server itself may be down as well.
NetTool Users Manual Unwanted protocols (when enabled) The purpose of the Unwanted Protocols feature is to enable you to find protocols that you do not want on the network. For example, if you have migrated away from NetWare on the network, NetTool will flag a device that still has NetWare configured on it.

Appendix C Glossary 10BASE2 10BASE5 Sometimes called ThinLAN or CheaperNet, 10BASE2 is the implementation of the IEEE 802.3 Ethernet standard on thin coaxial cable. The maximum segment length is 185 meters. Sometimes called ThickLAN, 10BASE5 is the implementation of the IEEE 802.3 Ethernet standard on thick coaxial cable. The maximum segment length is 500 meters.
NetTool Users Manual 10BASEF 802.3 A point-to-point fiber link. This is the draft specification for IEEE 802.3 Ethernet over fiber optic cable. Often called Ethernet, this IEEE standard governs the Carrier Sense Multiple Access/Collision Detection (CSMA/CD) networks. Typical cabling standards are 10BASE-T, 10BASE2, and 10BASE5. 10BASE-T 10BASE-T is the implementation of the IEEE 802.3 Ethernet standard on unshielded twisted-pair wiring.
Appendices C ARP (Address Resolution Protocol) Broadcast A member of the TCP/IP protocol suite, ARP is the method by which a station’s MAC address is determined given a station’s IP (Internet Protocol) address. A message that is addressed to all stations on a network. For Ethernet networks, the MAC broadcast address is FFFFFFFFFFFF. Attenuation Broadcast Storm A reduction in the strength of a signal; the opposite of gain.
NetTool Users Manual Client A client is a computer that makes requests of a server. A client has only one user; a server is shared by many users. CSMA/CD (Carrier Sense, Multiple Access with Collision Detection) A collision is the result of two or more nodes transmitting at the same time. Excessive collisions are most often caused by a problem with the physical media. In CSMA/CD, each node or station has equal access to the network. Before transmitting, each station waits until the network is not busy.
Appendices C Destination Address Ethernet The address of the station receiving a frame. Ethernet is a 10 Mbps topology that runs over thick coax, thin coax, twisted-pair, and fiber-optic cabling systems. DNS Domain Name Services provides a mechanism that allows users to remember logical machine names rather than IP addresses. DNS provides mapping between a machine name (e.g., www.fluke.com) and its IP address (e.g., xxx.xxx.xxx.xxx).
NetTool Users Manual Full-Duplex ICMP (Internet Control and Message Protocol) 10Base-T and 100Base-TX network operation using a switching Hub to establish a point-to-point connection between LAN nodes that allows simultaneous sending and receiving of data packets. Full-duplex performance is twice that of half-duplex performance. A 10Base-T fullduplex network is capable of 20 Mb/s data throughput, while a full-duplex 100Base-TX network is capable of 200 Mb/s throughput.
Appendices C Jabber Layer A frame greater than the maximum legal size (greater than 1518 bytes) with a good or bad frame check sequence. In general, you should not see jabbers. The most likely causes of jabbers are a faulty NIC/driver or perhaps a cabling problem. One of seven levels in the Open Systems Interconnection (OSI) reference model. See OSI. Jitter Variability in latency, or delay. If a network provides varying levels of latency (i.e.
NetTool Users Manual NEXT Ping Near-end crosstalk; crosstalk between two twisted pairs measured at the same end of the cable as the disturbing signal source. A network interface card is the adapter card that plugs into a computer to provide a network connection. Packet Internet Groper (ping) is a common method of accessing devices on a network to see if they are active. Ping sends a packet from one device, attempts to “bounce” it off another device, and “listens” for a reply.
Appendices C Remote Collision RJ-45 Connector A collision that occurs on the other side of a repeater. Since a 10BASE-T Hub is a multi-port repeater with a "segment" dedicated to each station, 10BASE-T collisions are remote collisions. A modular connector used for UTP wiring. The RJ-45 connector has eight conductors to accommodate four pairs of wires, and it has become the dominant connector used in Ethernet and Token Ring UTP installations.
NetTool Users Manual RTCP (Real-time Transport Control Protocol) Short Frame A protocol that provides insight on the performance and behavior of the RTP media stream. A frame less than the minimum legal size (less than 64 bytes) with a good frame check sequence. In general, you should not see Short Frames. The mostly likely cause of a Short Frame is a faulty adapter card or driver. Runts Typically defined as an Ethernet frame which is less than 64 bytes.
Appendices C SNAP (Subnetwork Access Protocol) Subnet An IP protocol that is an extended version of the IEEE LAN logical link control (LLC) frame. SNAP provides access to additional protocols and allows vendors to create their own protocol sub-types. A subnet is a section of the TCP/IP network. Each subnet has a unique subnet number and is connected to a router which enables connection to other subnets.
NetTool Users Manual Topology Uptime Topology is the organization of network components. The topology of Token Ring network components is a ring. The amount of uninterrupted time that a resource (such as a print server) has been available. Transport UTP (Unshielded Twisted Pair) Transport refers to the physical method by which data is transmitted (e.g., Ethernet, Token Ring, etc.). Different physical network hardware and cable layout are required for different transports.
