275NetBIOS over IP Troubleshooting T3Use the following check list to troubleshoot your network communication problem.Check Physical Media and Network Interface Cards1. Verify that the Device is powered ON.2. Verify that the Device and Workstation are using the correct cabling to communicate over thenetwork. Use category 3 UTP patch (NOT crossover) cable for 10 Base T communications, category5 UTP patch (NOT crossover) cable for 10 Base T / 100 Base TX communications, and Token Ringcabling for Token Ring networks.3. Verify that the cable at both the Device and Workstation is fully plugged into the Network InterfaceCard (NIC). Check the link light, which is typically a green LED, to make sure that it is lit. Typically,but not always, a second light on the Network Interface Card will be intermittently flashing, indicatingthe presence of network traffic. If neither of these lights is lit, there is a problem with the NIC.Print a Settings List at the Device and perform these tasks:1. On the Settings List, verify that "SMB" is enabled. If it is NOT enabled, to enable SMB, follow theinstructions supplied in the Microsoft (NetBIOS over IP) procedure in the NOS Selection section ofthis guide.2. On the Settings List, note that the default name of the Device's workgroup is Workgroup and that theDevice has a unique (SMB Host) name. To modify the Device's Workgroup or SMB Host names, ifrequired, use your workstation's Web browser to access the Internet Services (Web Pages) residingin the Device as described in the Configure SMB procedure in the Internet Services section of thisguide.3. On the Settings List, under the TCP/IP data label, note what method the Device is using to acquire itsTCP/IP addresses. If the method shown is Static, make sure that the Device has a valid IP address,Subnet Mask, and Gateway address for the network.4. On the Settings List, verify that DNS (or WINS, if using only a Windows NT network) is enabled. Theuse of Naming Servers is REQUIRED to resolve NetBIOS device names to IP addresses for packetrouting over the TCP/IP network. If in doubt as to whether DNS and WINS are enabled, verify thesettings following the instructions supplied in the TCP/IP Dynamic Addressing procedure in theNOS Selection section of this guide. WARNING: If the Device is NOT informed of the addresses ofthe DNS/WINS Servers, you may not be able to see or use the Device's NetBIOS name on thenetwork. Make sure that the Device is informed of the addresses of the DNS/WINS Servers, usingthe instructions supplied in the Configure TCP/IP Settings procedure in the Internet Servicessection of this guide.5. Under the Internet Services data label, verify that this feature is Enabled. If it is NOT, enable itfollowing the instructions supplied in the Network Connectivity section of this guide. You MUST usethis tool at your workstation if you need to change the Device's Workgroup name, the SMB HostName, the TCP/IP (internet) Host Name, or DNS settings. Note that when using DNS to resolve hostnames to IP addresses, the NetBIOS name (SMB Host) and the TCP/IP Host Name MUST be thesame.
