NT4 Server, SMC 1024DT 10/100 Switch, Win98 clients with 10/100 nics. TCP/IP, NetBEUI, &
IPX/SPX protocols. TCP address range 192.168.123.xxx. Some PC's will not connect to 1024 switch but work fine on our old SMC 10mbps switch which we want to move up from.
One PC works fne on 1024 switch in 1 location but move it to new location, no connection, despite changing cables & connectors. In all cases nic link led lights and 1024 switch leds for port light,
but activity led doesn't. Client self loop ping 127.0.0.1 passes. Ping to server times out, as with other clients. Maximum distance involved is about 20 meters max.
Could anyone please shed some light on why this might be?
Nic's are nearly all Trident TX.

Here's a few things to try.

First. Is the driver on the win98 machines set to AUTODETECT for its network speed / duplex? Some NICs have a problem with AUTODETECT trying fixing the speed / duplex in the driver. The one PC that doesn't work in onelocation - do other machines have the same problem when connected to that switch port? (could be dead port on switch). Do you have the Elite View software from SMC (downloadable for free from www.smc.com). Can 2 Win98 machines talk to each other? Ifyou do NET VIEW from a command line on the machines what do you get?

Changing NIC properties from auto-detect to a fixed value worked a treat. Thanks very much.

Remember that switch 'remember' where the connections are. Is this because of that ??
