PROXMOX crash when VM Windows is run

Clear message : http://s460547784.onlinehome.fr/share/PB1.pdf
Hello,

Student and passionate computer I start with Proxmox and I find myself confronted with some problems:
-My Linux VM work perfectly.
But when I create a Windows VM as am, after 5 minutes followed by the launch of the Vm (by booting the iso install Win 2008 R2) the Proxmox server is unreachable, all VMs are shut down and does not respond to ping.
Windows VM configuration:
boot: dcn
bootdisk: sata0
cores: 2
ide2: local2:iso/Server.2008.R2.SP1.FR.v666.5_x64.iso,media=cdrom
memory: 8192
name: WINDOWS-1
net0: rtl8139=26:BE:03:D7:E2:17,bridge=vmbr0
ostype: win7
sata0: local:104/vm-104-disk-1.vmdk,format=vmdk,size=40G
sockets: 4

Here I use VMDK but if I use QEMU does not work either.
