Su,
Adam is the author of Landshark and he'll certainly find a better (and permanent) solution, but here is what I do when this happens in VMware Fusion on my Mac.
If I've already finished starting the VM for the first time and see the message about "Network Interface not configured" on the VM console, I go to the "
Settings" button in the
Virtual Machine Library...
...then I select "
Network Adapter"...
...then change the setting from "
Share with my Mac"...
...to "
Private to my Mac"...
...and then restart the virtual machine. That generally brings up the correct networking on the VM.
I don't run on a Windows PC, but I suspect similar changes to VMware Workstation might help?
Hope this helps!
