Hi,

Please turn off power management for NIC if it is turned on.

Right click on the NIC and select Properties.
Click on Configure button
In the Properties window, select the Power Management tab and uncheck "Allow the computer to turn off this deice to save power"
Click Ok to apply the settings.

Hi SreRaj,
Thank you for your reply, You are advising that turn off power management for NIC should stopped the issue to reproduce, and I will surely check that. Can you please provide me more insight to disable on TCP chimney, whether it would be appropriate to disable it to attend the issue as well.

TCP Chimney Offload is a networking technology that helps transfer the workload from the CPU to a network adapter during network data transfer. The NIC adapter should be supporting this feature. Turning off TCP Chimney Offload may not increase the load on the server if the server is not transferring GBs of data over the network.

Please refer the following article for more information on disabling TCP Chimeny Offload.
