Hi folks,
One of our HP Workstation Z640 drops network connection occasionally, maybe a few times a day. It's also somewhat reluctant to connect to network shares after startup.
I have tried to change switch ports, and also ethernet cables to the switch. I have also made all BIOS, firmware, and driver updates. As a last resort, I plugged in a real cheapo, noname Realtek NIC in a PCIe slot. With the new NIC, the network shares come up directly after login, and there don't seems to be any drop outs.
We have got another identical Z640 workstation, that doesn't display those problems.
I would be grateful if somebody has got any ideas about possible ways to solve it.
Best regards,
Peter
