How to Disable NIC Power Management in Exchange Server
To ensure optimal network performance on your Exchange Server, it is recommended to disable the power management feature on the network adapter. Follow the steps below to configure this setting:
- Log in to the Exchange Server using an account with administrative privileges.
- Open the Device Manager from the Start menu or by running
devmgmt.msc - In the Device Manager window, expand the Network Adapters section.
- Identify the relevant network adapter. (In this example, the system is running on a VMware virtual machine, so the adapter appears as “VMXNET3 Ethernet Adapter.”)
- Right-click the network adapter and select Properties from the context menu.
In the Properties window, navigate to the Power Management tab.
Uncheck the option labeled “Allow the computer to turn off this device to save power” to prevent the system from disabling the network adapter during low-power states.
Click OK to save and apply the changes.
The NIC Power Management is turned off successfully on the Exchange Server.
When we run Exchange healtcheck again, you will see that the warning is gone.
