No RDP with VB 3.0.10 on W7_amd64 and Ubuntu 9.10_amd64

[sperelec]

I´ve installed VB on W7 with a Ubuntu guest with the above mentioned versions.
Everything ist working fine. The Ubuntu guest has network connection and it´s
also possible to use the internet.
If i connect to w7 via Remote Desktop (from another PC with XP) an try to start
Ubuntu i get an error message.
"Cannot open device "D:" ... and so on...
The error message is attached as a screen shot.

If somebody knows how to solve this please let me know...

Look at the connect shared properties of the RDP session and look at who you are via RDP, vista and w7 lets you connect with the same profile but with different sessions and such vbox can't find/access the vm.
