14.1 There is a problem with a ring station, a group of ring stations, the entire network, or a network peripheral accessing or using a particular application/group of applications, or certain directories/files on the network file server. First, check the network file server and any symptomatic ring stations for the following software and hardware configuration setup parameters and requirements: Make sure that the NOS network shell software, NOS NIC drivers, CONFIG.SYS, AUTOEXEC.BAT, and all the necessary network operating system files are set up for the respective NOS specialized configuration and NOS hierarchical directory structure. Check the NOS directory structure as it relates to the ring station and any respective network peripheral access. Check all the NOS security rights configurations. Make sure that all the necessary directories/files for all NOS applications on the network drive and ring station drives are set up correctly. Make sure that all the necessary hardware is installed in the file server/ring stations, configured correctly, and functioning properly. Check the respective NOS manuals for file server setup concerning network-software-vendor requirements for both software and hardware prerequisites and their respective configurations. Are any identifiable hardware or software configuration setup problems with the network file server? Take the necessary action to resolve the configuration problem and retest the ring for proper operation. If the failure symptom is gone, record the problem in the network maintenance and service log. If the failure symptom still exists, go to the next step . If there appears to be no problem with the file server or its setup, attempt to gather more conclusive fault-isolation data by running a protocol analysis session on the ring. Go to page 15 and focus on the problem by capturing and viewing the high-layer communication processes. If after using this page you cannot conclusively locate the problem and continue to find failure symptoms that point to the network file server problem, reference both the NOS software and the particular file server/hardware manufacturers' instructions.
