Re: Frequent Netwok Up/Down link

Ok, setting the affected ports to 100/Full works. Since it is a gigabit switch and half the clients and the server could use that gibabit speed, I would prefer that. So any ideas on why the link kept going up/down when the ports were set to auto?

Then you might go into the switch's management console to see what it says. And, you can lock down the switch ports to 100/full, as well - at least for the ports that the workstations & server(s) use.

I will attempt your suggestons now.

I do recommend that config anyway, as a matter of course. It prevents NICs
'flopping' between settings when they, and the switch, try to agree on the
best config.

A Dell PowerEdge 5324 (24port gigabit swtich) is plugged into the
internal NIC of the SBS box. This switch was recently installed as
an upgrade, but I am told this issue described below has been going
on with the prior switch also. Some computers were replaced just
prior to me looking after the network, but the NICs are Intel
PRO/1000 PL and Intel PRO/100 VE.

I'm presuming this isn't a managed switch....
Set all your clients' NIC cards to use a specific speed/duplex
setting, not autosense, and see if this goes away.

From what you are saying there is no indication that this is SBS
related. Give us some more info on your network. Which switch are
you using, what NICs are used on the workstations?

Not sure if I should post this here or not, but since we are
running SBS 03
Pro, I thought I ask. Out managed switch is logging link down /
link up status changes for praticaly all the ports, except for the
port that the SBS
box is on. The event logs for all affected computer are full of
events like
these two below. I have inherited this network, but I do not have
this issue
at all on two other networks that I have configured.
So as much I have searched for these error, I found no real
solution yet. Any thoughts on when the ports may be switching
satus every 4-6 seconds? They come back within a second, so the
users do not notice, but there is one
app that is running on TS on a second server that just terminates
the connection once or twice a day. Im trying to figure out if
this is switch or
SBS related.

THanks,
Attila
