I was think this. But now i found windows make it independ on physical cable status. Windows always trying to establish connection it happens (as i suspect) because vbnet send signal "Cable connected". Then windows show looking for IP icon on task bar, then show "No network cable". And it happens again and again.

Still don't fully understand your scenario. Is the virtual network cable (in the VM network settings) connected or disconnected?
If it is disabled then the guest will detect that and probably complain.

Got the same issue with 3.0.6 r52128 Host : Linux Ubuntu 9.04 Guest : WinXp Net Adapter 1 : Bridge -> wlan0 Disconnected (unchecked in adapter list) Net Adapter 2 : NAT Connected Net Adapter 3 : Host-only Disconnected Net Adapter 4 : Bridge -> eth0 Disconnected
Every few seconds, all the supposed disconnected adapters (icons) flash, like in a normal DHCP negociation, and then the anoying message "Cable unplugged". So, I have to disable them from the guest OS to be able to work without bubble messages poping up every few secs.

ctroncoso, please attach a VBox.log of such a VM session when you experience these messages in the guest.

axet, still unable to reproduce. I have a setup which is mostly the same as yours (3 x pcnet, 1st: NAT, 2nd: wlan0, 3rd: eth0, WinXP guest). Currently wlan0 is not connected (I'm connected through eth0) and there is an exclamation mark on the Windows guest but no annoying message boxes. Do you have some system tool installed which is fiddling with the network connections?

annoying message is windows tool tip message appears each few seconds. which told about "A network cable is unplugged". see (Screenshot.png).
i have no special application installed, this issue appear on clean windows installation.
please check all contitions:
- three interfaces
- one nat, default connected
- two other enabled but no virtual/physical cable connected. (Screenshot-Additional Options.png)

Fixed in r24455. The fix will be contained in the next release. Actually the guest was confused because some packets arrived its RX buffers even if the link down.
What do you mean by remove "cable connected" in options menu? If you click on that menu, then the virtual network cable is disconnected and Windows will detect that, regardless of the state of your physical network cable. Or did I misunderstand you?
