During those slowdowns, is it that you can't access the server, or that you can't access any other machines on the network? That distinction is important in diagnosis.<br><br>Rather than wiring - my inclination would be a faulty switch somewhere, perhaps overheating and dropping down to hub mode?<br>

Hey all, happy new decade.<br>
<br>
On a network I am looking after, we are experiencing random slowdowns<br>
between 0 and 5 times per day. They last between 20 seconds and 200<br>
seconds each and bring everything to a halt. Then the problem disappears<br>
and everything is fine again - just like that...<br>
<br>
Have trawled syslog, messages etc on the server during those times - and<br>
absolutely nothing out of the ordinary is showing up.<br>
<br>
I think therefore that the issue is down to some sort of magnetic or<br>
electrical interference, like a faulty lighting circuit or some leery<br>
telephone cable crossing the RJ45... there is one place where I see a<br>
lighting cable is packed into the same trunking as the RJ45 for a<br>
stretch of about 5 meters.<br>
<br>
Could this affect things - or does anyone have any ideas of how to<br>
diagnose such a problem further?<br>
