Continuing on from previous post regarding the issues with OneCare, Trend and VPNs I have run into another problem with OneCare. This time it is preventing the beta of the Windows Mobile Device Center from connecting to my mobile device (or perhaps that should be my mobile device from connecting to WMDC). Note that this behaviour is consistent with the default Windows Firewall that ships with Vista. This leads me to believe it is probably an issue with WMDC rather than explicitly OneCare; However, it is an issue that both teams need to address.
