TCP/IP is not enabled for this connection

I have a laptop that is running Vista Home Premium SP2 running Sun VirtualBox that is running a Windows XP Proffessional, i log in to the computer and connect the laptop to the router, it opens up the internet on the Vista OS but after that i load up the XP VM, and it won't connect to the internet at all. It picks up a LAN, but doesn't get any sort of IP address, so i open up the Network Connections and try to repair the connection but up pops the error message 'TCP/IP has not been enabled for this connection.'

Any advice would be greatly appreciated.

Recently they installed a second AV program over our current one, they installed 'CA Security' over our 'Trend Micro' so that they had 2 AV's installed at the same time. Could that have had anything to do with it?

It is thinkable that the CA security product has something to do with this, but that depends on the way you configured the guest network.

If it is run in NAT mode, the guest will simply share the host's ethernet connection, and third party internet security shields will not interfere.
But if it is set to 'Bridged' mode, then the guest will contact the hosts gateway/router like it was a separate machine on the LAN, and request its own IP address. In this case, a security shield that protects (= blocks/allows) LAN traffic might very well be expected to interfere.
Check the CA Security settings and try to find out whether it lists your ethernet drivers somewhere. Usually the ones for which LAN traffic should be allowed must be specified. Accept all traffic on all adapters that have "Virtualbox" or "Vbox" in their name.

sounds fairly obviously but have you gone into the properties for the network adapter? make sure that TCPIP v4 or v6 is enabled accordingly.

Ok, its been resolved, what happened was that the person was using his wireless, and the connections haven't been bridged for wireless, and thats why it isn't working. Thanks for your help Torimar.
