Hi Have joined to let people know about the problem with the Belkin High Speed Wireless G Card running WinXP Pro. A process called WinXPDisableZeroConfiguration.exe starts and takes up to 100% of the CPU all the time. The exe is installed as part of the driver for the Belkin card. To overcome this, visit: http://web.belkin.com/support/download/downloaddetails.asp?download=1430&lang=1 to download and install the replacement Belkin driver. Note: the installation starts with a complete Belkin uninstall and power down!! Very strange but the subsequent install corrects the problem. Hope this helps a few of you.
