Windows Virtual Machine not seen by host (Mac OS X) using VMWare Fusion

Windows Virtual Machine not seen by host (Mac OS X) using VMWare Fusion

I installed Windows XP with VMware Fusion on my MacBook and while internet works, Windows can ping the Mac, etc. from the Mac or any other machine in the network we can not see the Virtual Machine. In between, I use bridged option and obtain the the VM's IP dynamically; tried also static assignment from the free addresses but the problem persisted.
