My client has a W2k Advanced Server that has been running smoothly for about one month. 33 W98 & W98 SE clients. For the past 3 days, all users have been getting cut off no matter what application or session they’re running. They’re connected ok forsome time then get randomly disconnected. Have checked Licensing, Event viewer,Device manager, both network cards(two on server, same subnet). Also have rebooted Server. Can’t find any obvious problem. Users get error: Lost connection, please check computer application is running on”. Do not have electronic analyser to determine if physical layer problem, but can ping ok. Switch indicators show good.
