I just upgraded the network driver (broadcom) on my laptop under Vista RTM.
The Vmware Bridge where still there, but no VM could access network through the Bridge.
To solve this issue, what i did:
-Remove the Vmware Bridge procotol on the network card
-Reboot (marked for deletion)
-Install again theVmware Bridge protocol
I needed some times, since i also upgraded the wmare tools inside the VM and i was trying to use the secureclient inside the VM (i didn't remember that i upgraded the network driver yesterday in the first place)
