I searched on the internet but all issues have Ubuntu as the Guest. I have VMWare Workstation 8 wherein Windows 7 is installed.
If you can't get anything else to work, setup a "host only" adapter on VMware and for guest OS. Then set them to be in the same IP range, i.e., guest could have 126.96.36.199/255.255.255.0 and host could have 188.8.131.52/255.255.255.0.
Then try to ping from one to the other, if it works you're in. Then from the Ubuntu 12.04, hit Alt+F2, type
and then enter to connect. Put 184.108.40.206 as the domain and the windows user/pass.
