Host Can't Access VMs

I recently upgraded from VMware Workstation 8.0.5 to 8.0.6, and now my host can't access my VMs.  I am using bridged mode, and:

1.  Before the upgrade to 8.0.6, my host could access (for example, ping, SSH, RDC, etc) my VMs.

2.  After the upgrade to 8.0.6, my host can't access my VMs.

3.  My host can access VMs on other hosts.

4.  My host can access other physical machines.

5.  Other physical machines can access my VMs.

6.  My VMs can access each other.

7.  My VMs can access my host.

8.  My VMs can access VMs on other hosts.

9.  My VMs can access other physical machines.

I have installed the 8.0.6 version of VMware tools on myVMs; my host is a Windows 7 x64 machine; my VMs are a mixture of Windows 7 x32, Windows 2000, Windows 2000 Server, Windows 2003 Server Standard Edition, and Windows 2003 Server Enterprise Edition machines.  As far as I know, I have not changed any settings on any virtual machines either during or after the upgrade to 8.0.6.

Anyone have any ideas?

Thank you.
