Hi,

I can't ping form Host -> Guest or Guest -> Host.
But
Host ping to -> Internet/Router works
Guest ping to -> Internet/Router works

Do have any Idea to fix it?
Thank you vor helping me.

PS: Sorry for my bad englisch.
PPS: A few day ago i was installing Win XP-Mode on Host W7, but i was deinstalling yesterday.

Sounds like you have a firewall issue or you have installed a driver ( because of xpmode ) that is not compatible with the VBox driver. If you are sure that all drivers were removed then do a cold boot of the host. ( shut down wait 20 seconds and the strart )

Great, thank you.
It works now.


VirtualBox-x.x.x-yyyyy-Win.exe -msiparams NETWORKTYPE=NDIS5
that was the solution
