I have installed hamachi on my windows 7. When I change my network adapter, after a while my computer cannot resolve DNS addresses. For example, at home I use WiFi. I suspend my computer and go to the office. At work I connect to the wired Ethernet connection (i.e. change the network adapter) and after a while my system is unable to resolve DNS addresses.

Solution for this is either to reboot the computer or disable the hamachi adapter from Network Connections (Control Panel\Network and Internet\Network Connections).
