Network Link Disconnected I350 T4

[bcu]

The Intel NIC I350 T4 & X710 connected to cameras for image streaming by GigEVision protocol is used in our industrial application.

The Windows Eventviewer shown "Network Link Disconnected" (source : e1rexpress, ID : 27) randomly while the streaming was interrupted due to timeout.

What does the source name "e1rexpress" stand for? Which reasons could be behind such message?

Hi Alfred,

now I observed following Windows Eventviewer registration :

A service was installed in the system.

Service Name:  Nal Service

Service File Name:  C:\Windows\system32\Drivers\iqvw64e.sys

Service Type:  kernel mode driver

Service Start Type:  demand start

After this action the NLD (Network Link Disconnected) occurred.

Please advise!
