2. Solution The node s connection to the Microsoft network is not configured correctly Verify this cause by checking other applications that use the network such as Network Neighborhood and File Sharing Reconfigure the network connection and parameters such that you can see nodes in Network Neighborhood and browse into their file shares Other LUN Works nodes are not in the same LAN domain or workgroup Verify this cause by using Network Neighborhood to determine if other nodes are on the network and which domain or workgroup they appear in Move nodes into the same domain or workgroup A 4 Third Edition 313410503 Errors Cause Solution Nodes are inaccessible via TCP IP due to incorrect configuration Verify this cause by using the command line ping utility to determine if nodes are accessible Four possible solutions are listed below e Ensure that TCP IP is installed If not install it from your Windows NT CD ROM e Check the IP subnet numbers and masks on local and remote nodes and make sure they match e Check the routing tables on local and remote nodes e Check the hardware components such as LAN cables hubs and switches Intermittent Mouse Cause Solution A Fibre Channel communication problem is causing a high rate of adapter resets in the HBA driver Check all Fibre Channel connections and storage If you are using a switch
