Just noticed I'm having some trouble with networking on Ubuntu (Karmic) guests on a Win 7-64 host.
The networking will work at times however if the guest is (resumed) it will fail to connect.At this point no Ubuntu guests will be able to connect using Bridged/Nat networking.To get things working again I need to reboot the Host.
I've tried rebuilding the Linux Guest package. This has just begun happenning in the past week or two. I'm not sure if it might have something to do with some recent patches from Ubuntu or because I upgraded VM-Ware Player to the latest point release.
