Windows Known Issues
Procedure for Installing and Upgrading Drivers and Utilities
Intel does not recommend installing or upgrading drivers and Intel® PROSet software over a network connection.
Instead, install or upgrade drivers and utilities from each system. To install or upgrade drivers and utilities, follow the
instructions in the user guide.
"Malicious script detected" Warning from Norton AntiVirus During PROSet Uninstall
The Intel PROSet uninstall process uses a Visual Basic script as part of the process. Norton AntiVirus and other virus
scanning software may mistakenly flag this as a malicious or dangerous script. Letting the script run allows the uninstall
process to complete normally.
Windows Code 10 Error Message on Driver Install or Upgrade
If you encounter a Windows Code 10 error message when installing or upgrading drivers, reboot to resolve the issue.
Advanced Properties Settings Change While Traffic is Running
In the Advanced Properties tab of Intel® PROSet, parameters should not be modified under heavy network loads. Other-
wise, a reboot may be required to make the changes effective.
Unexpected Connectivity Loss
If you uncheck the "Allow the computer to turn off this device to save power" box on the Power Management tab and
then put the system to sleep, you may lose connectivity when you exit sleep. You must disable and enable the NIC to
resolve the issue. Installing Intel® PROSet for Windows Device Manager will also resolve the issue.
Intermittent Link Loss and Degraded Performance at High Stress Can Occur on Windows Server 2012
Systems
In a Windows Server 2012-based system with multi-core processors, possible intermittent link loss and degraded per-
formance at high stress may occur due to incorrect RSS processor assignments. More information and a Microsoft hot-
fix are available at:

Intel 10GbE Network Adapter Known Issues
ETS Bandwidth Allocations Don't Match Settings
When Jumbo Frames is set to 9K with a 10Gbe adapter, a 90%/10% ETS traffic split will not actually be attained on any
particular port, despite settings being made on the DCB switch. When ETS is set to a 90%/10% split, an actual
observed split of 80%/20% is more likely.
Supported SFP or SFP+ Module Not Recognized by the System
If you try to install an unsupported module, the port may no longer install any subsequent modules, regardless of
whether the module is supported or not. The port will show a yellow bang under Windows Device Manager and an
event id 49 (unsupported module) will be added to the system log when this issue occurs. To resolve this issue, the sys-
tem must be completely powered off.
Link Loss on 10GbE Devices with Jumbo Frames Enabled
You must not lower Receive_Buffers or Transmit_Buffers below 256 if jumbo frames are enabled on an Intel(R) 10GbE
Device. Doing so will cause loss of link.
