After Installing Oracle Virtual Box and changing the network adapter to bridged mode cant access my server

Hi ,

I have installed Oracle Virtual box on windows server 2008 r2 hosted on 1und1.de.

Till installtion and setting up untun on virtualbox it was fine, but once i changed the adapater to bridged mode. I immediatly lost connectivity with my server and now cant access.

It is now 2 days i cant access my server and neither ping it, also the website hosted on it is also down.

The 1und1 has following 2 options

1) using putty i can connect to server command prompt using administrator but cant run any gui application

2) Server Rescue mode: where i get special environment to start, stop services, access registry and command prompt.

Till now i have tried lot of setting to enable network connectivity but not able to success

This is the result of Ipconfig /all
