ip-address

I have a network with the following:

Cable modem with static IP address
Router
Desktop - Win 7
VM Host - VMware ESXi 4.0
A couple of VM Guests - Windows

Every now and then my Win 7 PC is unable to access some of the VMs. When I ping the VMs by their domain name their IP address shows up as the IP address of the cable modem.

Sometimes I can fix it by running ipconfig /flushdns. The IP address will reset back to what it was supposed to be, but occasionally it wont work.

Why does this happen and how can I fix it?
