What kind of host operating system do you have (windows/linux) ?
Did you set up the network devices in teh vmware - it's kind of tricky
Did you set up the network in your Mandrake
if you have isntalled the vmware on linux
when you do
look for entries like vmnet and vmmon
vmnet 18368 2
vmmon 23052 0
than vmware is useing a private loopback network
on linux run vmware-config.plto reconfigure your vmware
