Cannot install Windows 2008 R2 as a guest

[Mury]

Running VirtualBox 4.0.10 on Debian Lenny 64-bit host installed on Dell R310. Successfully created a Windows 2008 64-bit guest VM, however Windows cannot install. The VRDP session terminates 30 sec after Windows install starts. I tried to replicate the problem on Supermicro hardware, but I was able to successfully install Windows there. I also exported the VM from Supermicro and imported it on the Dell R310 and had the same problem - VRDP terminates 30 sec after Windows start. Below is the script used to create the guest VM and also the log files are attached.
