To whom it may concern,
We have 5 computers who tend to crash outside business hours on a whole 1500+ computers we take care of. All of the have the 82579LM NIC and are installed with Windows 10 Pro OS. In 4 cases it crashed the network, causing a broadcast storm, and required a switch + router reset after the computer was hard-rebooted.
The following actions were taken :
-Updated card with Intel and/or Lenovo latest drivers
-Disabled any form of sleep mode (in the driver's nic and Windows)
-Installed all the Windows Updates we could
In the morning, the computer's monitor is all black.
The only way we could fix this issue was by replacing the NIC with a USB one, and disable the internal Intel NIC. I just tried to install Caffeine software to prevent completely the computer from going to sleep but this is hardly a solution since it will also prevent the monitor from going to sleep.
Any idea what could be done?
Thank you all!
In order to get you the best support possible, we have moved your thread to the /community/tech/wired Wired Ethernet Support Community.
Thank you for posting in Wired Communities. I am sorry to hear what happened, can you share more information below:
1) What is the exact motherboard or system model the 82579LM embedded on?
2) What is the driver version?
3) Was there any recent changes made on the 5 computers?
4) Does the problem exist if 82579LM wake up from sleep mode?
Have you tried disabling any sleep mode setting in BIOS (in case there is).
Please feel free to update me. Thank you.
