Outdated Intel I350‑T4 Driver (e1r65x64.sys) Causing System Freezes and Hardware Resets

[Sysadmin_random]

Hello,

I am experiencing recurring system freezes and hardware resets related to the Intel I350‑T4 network adapter on a Windows Server 2016 system. The issue appears to be caused by the outdated driver e1r65x64.sys, which is currently the latest version available for this OS.

Symptoms observed:

• Random system freezes under network load
• Network adapter resets
• Event Viewer repeatedly logs Event ID 10400 (NDIS)
• After each occurrence, the system recovers but the network interfaces temporarily drop

This behavior strongly suggests that the existing driver for the I350‑T4 on Windows Server 2016 is no longer stable or compatible with recent system updates.

Environment details:

• Hardware: Intel I350‑T4
• OS: Windows Server 2016 (fully updated)
• Driver file: e1r65x64.sys
• Issue: Hardware reset / NDIS Event 10400
• No updated driver package available for WS2016

I would like to know:

1. Is Intel aware of stability issues with the current I350‑T4 driver for Windows Server 2016?
2. Is there an updated or alternative driver available that resolves these problems?
3. If Windows Server 2016 is no longer supported for this adapter, is there an official Intel statement confirming this?

Any guidance or updated driver package would be greatly appreciated, as this is affecting a production environment.

Thank you.

Hi, sorry for the delay and thank you for your reply.

Regarding point 1:
Unfortunately, I do not have physical access to the server, as it is located in a remote datacenter. The system is managed remotely via Lenovo XClarity. Because of this, I cannot take front and back pictures of the NIC card.
 

However, I can provide all available identification details from XClarity / system inventory (NIC model, part number, FRU, firmware version, etc.) if that helps.
 

Regarding point 2:
The Intel I350‑T4 NIC came pre‑installed with the system by the server vendor (Lenovo). It was not purchased or installed separately.

Regards!

Hello Sysadmin_random,

Greetings!

To help us better understand the cause of the issue, we kindly request you to confirm whether this behavior started immediately after updating to this driver, or if it coincided with any other system changes (such as Windows updates, BIOS/firmware updates, or hardware changes).

Good morning, there are no changes or updates; it can only be commented that it coincides with backup processes carried out with Commvault, but it must be said that the backup is performed daily and only fails on Saturday night to Sunday every few weeks.

Thank you for your patience. Based on the SSU log the current driver version is 12.15.184.0 and the latest driver version for i350 is e1r - 14.0.6.0.

We recommend updating the driver and let us know the status.

Please find the driver package link below, along with a screenshot of the version details for Windows Server 2016.

Hi!

Thanks for the reply; what I wanted to do was update the firmware from XClarity, would that be a good option? I've attached an image of the driver and its version.

Hi Sysadmin_random,

Greetings!

Thank you for your patience. We recommend that you try updating, but we do not have the steps since this is a Lenovo xClarity environment.
