Microsoft recently changed the Default Dynamic Ports used in Windows Vista (all versions) and Windows 2008 (all versions). Default Dynamic Ports have been changed from 1025 through 5000 range to 49152 through 65535 range. SmartNAVI (and the older discontinued SmartSync) uses 49152. Microsoft has changed the port range to comply with the Internet Assigned Numbers Authority (IANA) recommendations. This affects NS2300N and NS4300N. Details from Microsoft on the changes is located here:  http://support.microsoft.com/kb/929851

How to apply workaround:

1. To apply the workaround under Vista and Windows 2008, UAC (User Access Control) must be disabled. To disable UAC, proceed to Control Panel > Users Accounts > Turn User Access Control On or Off. Reboot is required once change has been made.

2. After Reboot, open command prompt (located under accessories on the Program Menu under Start). Type each line and then press "enter". Reboot when finished and then enable UAC (then reboot again).

netsh int ipv4 set dynamicport tcp start=1025 num=3975
netsh int ipv4 set dynamicport udp start=1025 num=3975
netsh int ipv6 set dynamicport tcp start=1025 num=3975
netsh int ipv4 set dynamicport udp start=1025 num=3975

Permanent Solution: Will be available in the next few weeks. If you apply the workaround above, you will need to reverse once the new version of the Firmware and SmarNAVI is available.

3. Reversing Changes:

To reverse the changes and restore Dynamic Ports to Vista/2008 default values, use these paramaters (following same instructions above):

netsh int ipv4 set dynamicport tcp start=49152 num=16183
netsh int ipv4 set dynamicport udp start=49152 num=16183
netsh int ipv6 set dynamicport tcp start=49152 num=16183
netsh int ipv4 set dynamicport udp start=49152 num=16183
