Using the information provided [http://support.microsoft.com/kb/120752/EN-US here] I've found out that the culprit was the VirtualBox Host-only Network Adapter.
Anyone experiencing the same problem?
Any suggestions on how to further debug/solve it?
Thanks in advance"	defect	closed	network	VirtualBox 4.0.2	fixed			Windows	Windows
