Ethernet Connection Lost in Vista Ultimate
Computers using the Microsoft Vista Ultimate operating system may lose Ethernet communications with vbSeries instruments following communication via USB. This is the result of a network protocol incompatibility. To resolve this problem disable support for the IPv6 network protocol in Vista.
- Navigate to Start>Control Panel>View network status (this is located under the Network and Internet heading).
- Click Manage network connections on the left-hand menu.
- Right-click the Local Area Connection #X icon (the correct icon can be identified by the sub-heading 'vbX #X' where 'X' is the USB port number) and select Properties.
- Under the heading 'This connection uses the followng items:' deselect the checkbox beside Internet Protocol Version 6 (TCP/IPv6).
- Click OK.
Note: Disabling IPv6 will prevent you from using Windows Meeting Space or any application that relies on the Windows Peer-to-Peer Networking platform or the Teredo transition technology. If you wish to use these applications, simply re-enable IPv6 support. Ethernet instrument connections will be unaffected by the reactivation of IPv6 support as the compatibility problem is resolved by the initial performance of the procedure above.
