Lose internet connect when switching to Bridged from NAT mode

[jbass2000]

Host: iMac running OS X Leopard connected to Home Network via Airport Extreme (1 Gig) wireless set up as an access point (not a router).

Guest: Windows Vista Home Premium with latest updates

Version: Fusion 1.1

I can't seem to be able to select the Bridged configuration without disrupting my network connection. If I switch back to NAT is is still dead unless I suppend the Guest and reboot the host. Then I can run in NAT mode but not Bridged.

This problem first showed up after upgrading from 1.1 Beta to 1.1 RC and upgrading to Leopard on Host machine (not a fresh install, nor an archive & install).

Things were working fine until I saw a notice that my VM Ware Tools were out of date and to click to upgrade. After doing so, the problem showed up.

I have uninstalled the new Fusion 1.1, upgraded the VM Ware Tools again as requested, and I still can't connect to the network in Bridged mode. I have checked the settings on the Airport Wireless Base Station and nothing seems out of the ordinary either.

I have looked for similar issues and see many networking troubles but have not seen this particular problem posted. I did run Repair Permissions as one thread suggested but it didn't seem to have any effect either.

Any suggestions would be appreciated.

NAT and Bridged modes don't use IP addresses that are compatible so there is a disruption needed for the VM to acquire a new IP address. You can force this manually on the Windows command line (Start > Run > cmd) with these two commands:

ipconfig /release

You should see the IP address change to 0.0.0.0

ipconfig /renew

For NAT the IP address will change to a predictable internal address like 192.168.x.y or 172.*

For Bridged, this will be an address from your local DHCP server which could be 192.168.0.x or 10.x addresses.

Thanks for the help. I ran the cmd line as suggested but I received an error message saying it had timed out. So I exited the cmd line interface and restarted Vista and it worked. Don't know why it timed out, but I am now connected via Bridged mode so I am happy.
