SmoothWall – Allowing Windows Updates and Windows Activation

KB ID 0000441 


I’ve had fun this week installing a new virtual environment for a client with a SmoothWall firewall. It took a call to SmoothWall support for me to get Windows updates to work, then after activating a few 2008 R2 servers via phone, I was motivated to get online activation running as well.

Windows Activation Error – (We are being blocked by the SmoothWall Proxy).


A problem occurred when Windows tried to activate. Error Code 0x8004FE33
