nics keep dropping their connections for a second

This may not work on this area.
I have a SonicWall 1260 security device that has basically switch ports on it.  ALLsix of my servers would disconnect from it at the same time for 1-2 seconds and then come right back up.  SonicWall was no help.  Watching the switch lights they would go out on the server ports at same time servers lost connections. (go figure right?)  But not the AP unit or the WAN or the uplink to another switch.

Finally I set all the nics and ports to 100mb\full duplex.  That fixed the problem on three servers.  Three are still doing it.  They are all the same Dell PowerEdge 2800s with Intel Pro 1000 MT nics.

Please any ideas would be great.

Thanks,

Ok, maybe the driver changed for the NICs in one of MS updates and you should check to see if Intel has a later driver, or consider backreving the driver to an earlier Intel or MS version.  

Maybe there is spyware on one of them, or the NIC on one of them is bad, and it is sending out garbage confusing the sonicwall switch which is resetting.  I am guessing.

You don't have an extra 100mbps switch lying around to put in front of the sonicwall?

Try 100 Mbps auto on the switch and nics that still don't work.

Double check you power equipment - UPS, powerstrip, etc.  Is the Air Conditioning coming on when this happens, lights dimming?

Hi dakers2,

sounds to me like a firmware issue on your sonicwall - can you update it for me

Call Dell.  Put a small dell gig switch in front of the sonicwall.  Sounds like the sonicwall is going bad.  -gsgi

sonicwall already replaced the unit.  No fix.

I had a cisco switch and put the three dell 2800 poweredges with the Intel Pro 1000 MT nics on the switch and jumped that to the Sonicwall 1260.  Never another error.  Must be an issue with the Sonic wall nics.  Even though this was the second unit.

Is probably SMTP, Qos, Trunking, Rip, Spanning Tree ... something was confusing the sonicwall....

Now you have amo to call sonicwall or write them, and say hey, it's not the intel nics...  I bet sonicwall releases a software upgrade, you can't be the only one to have this issue, the intel MT 1000 is too popular.

Well, I am way out of my knowledge base here, but when the dell systems, by the way, laptops, desktops, and my servers are all dropping off, but when they come up they list in the event log that they detected Spanning Tree protocol.  gsgi you make it sound like they shouldn't???

if spanning tree is running on the sonicwall turn it off.  spanning tree runs on some switches by default.  people argue about whether or not it should be turned off.  what i did on purpose when i put in my dell servers, was connect them to a dell switch, then that switch goes to my main switch...  i figured this would be 'pretty safe' that they configured their nics to work with their switch.

Spanning tree takes loops out of a network, usually in a WAN.
