Remote Desktop Disconnected - error in data encryption

We've just rebuilt a Dell 2950 system  running Broadcom NetXtreme II NIC's with Windows Server 2008 64-bit for a client and had issues with RDP dropping the session stating "error in data encryption"

The fix is simple, you need to disable IPv4 Large Send Offload on the network card - either from Control Panel - Network Connections or using the Broadcom Advanced Control Suite
