Dropped Connections

[talkster5]

Hi,
I have a Cisco 1924 and I am having a few problems. I have 7 devices plugged into the switch of which 5 work perfectly fine but in the past week I have put 2 new devices onto the switch of which both will loose connection every now and then. The devices do not loose the connection at the same time but they seem to go down for about 5 minutes and them come back perfectly fine as they were before. I was just wondering if anyone knew or had any recommendations as to what to do to try and fix this problem.

Thanks.

Just another piece of information I have discovered if it helps. When the machine is responding the mac address for the device will appear in the mac table but when the device appears down the mac will not be listed. However the link is still shown as active on the port list.

Perhaps you have a speed/duplex mismatch. Since that switch is a bit of a dinosaur, you may need to hardcode the speed settings on both the switch and the devices you are plugging into it. What kind of machines are losing their connection?

Hi,
I have a Dell SC1425 Windows 2003 machine and a KVM over IP unit which seem to be having the problems. As soon as I add the MAC address' into the static unicast table they seem to work almost fine but they still have the occasional drop but only for a minute or so compared to the few hours that were happening before.
