complete these steps:
1. From the start menu, open the Network & Dial-up Connections folder located in
the Settings menu.
2. Double-click the LAN connection of the interface you want to disable TCP Offload.
3. Click the Properties button. Clear the box labeled Alacritech TCP Fast-path driver .
Click OK .
4. Restart the engine.
When uninstalling the
Alacritech TCP Fast-path
driver, an error message
appears with the message:
“Could not uninstall the
Alacritech TCP Fast-path
driver component. The error
is 0x800F020B”
No corrective action is necessary.
