The first question to be asked on WOL is did you enable S3 in your BIOS during the installation of XP Pro or was it later changed? Windows XP flavors sometimes will make it very difficult for WOL if the sleep S3 mode was not enabled within BIOS during installation. There are afew work arounds that can be used but I've found my only solution was to reinstall windows after my BIOS was set to S3.
