we have a strange problem since severals weeks.

in a same subnet, it's very difficult to join another computer, just with a
ping.

When we ping the other machine, the first "ping" is ok and then after it's
no more possible to join the machine.

If we made a arp -d of the @IP of the computer then it works one time again
and then not yet ... and so on.

We are in a DNS / DHCP / NT4 environment.

We have try to configure locally the both computers, with fixed @IP and uses
of the lmhosts file and so on ... without success......

When we connect the two computers together with a cable, it's OK ....

Have somebody has already got this kind of strange problem ????

Thanks for your help !

You say it's ok when join the two computers together with a cable? Sounds
like the hub/switch is bad?

I don't know ... maybe.

It's an Alcatel OSR. What is strange is that if we configured the computers
with static @IP adress and so on, it does not change anything and each time
we delete the destination @IP with arp -d, it run good one time.

I'll try to check the switch log tomorow morning.

Rgds,
Pascal.
