Network goes AWOL after a couple of minutes (pt 2)

Hi

This continues the issue raised here:

http://groups.google.com/group/microsoft.public.backoffice.smallbiz2000/browse_thread/thread/c5eb3d85f5853655/01915ae1a5b1d808?lnk=st&q=robsavage&rnum=2#01915ae1a5b1d808

Since then, the issue has come back repeatedly, and no matter what
processes of elimation we try, we canot nail the problem down.

For the past 2 months, they have had my own Cisco 2950 (not a 2940 as I
said before) in place and had not a single problem. However, I want my
switch back now!

I am typing out a quote for a new Cisco switch, but expect them to ask
why they should pay several hundred GBP just because we cannot identify
the cause of the problem. I'm also dead nervous that if we sell them
the switch and then the problem does happen again....!

To recap - network goes down intermittently, with all lights lit up on
the switch. Restart the switch and all is fine again.

I have since plugged the server into the firewall so that in these
situations, at least their mail server is still up and running to
collect mail. But the problem remains.

So it ain't the server causing the issue, as all that is connected to
the switch when it goes down now are PCs and a printer.

It just baffles me why the Cisco switch is so solid in this regard as
opposed to the other switches. We had the original Dell unit back in
place a couple of months ago, and they were getting the problem several
times per week. I installed the Cisco, and there's not been a single
occurrence since.

Any further suggestions would be greatly appreciated, else I shall have
to email them the quote!

Cheers

Rob
