I have solved in past this communication issue between host/guest OS (while rest of network working fine) by DISABLING the TCP/IP Offload engine (TOE) on the host OS network adapter, that was bridged into the guest OS. That was on DELL PE 2950 with broadcom NIC. After disabling the TOE on the underlying host OS, everything started to work fine.

Hope this helps someone.
