We have three netware 3.12 servers up and running in our lab. One is Primary and the another one is backup and the last one is for accounts department.All the servers & nodes are connected by BNC cables. Recently we shifted our servers to some other location. That day onwards our Accounts department server is detaching ityself from the network automatically. In other servers console command DISPLAY SERVERS not showing this accounts server. if i use RESET ROUTER in the accounts server's console, it's coming in to the network and the nodes can access this server. What's the problem..??? 15 mins once we are typing RESET ROUTER in the accounts dept server console . then only it's accessible by the nodes. Where's the problem...??
