iSCSI wizard hangs in my VM, why?

hi there,

I am running three VMs in my host (Windows 7 OS, 64 bit, 8GB RAM).

My goal is create a cluster between node 2 (2012 DataCenter OS) and node 3 (2008 R2 Enterprise). Due to I am at home as the very first point i would need to create a Virtual Disk and then assign a LUN.

I've already installed iSCSI Target Client in my node 3.

Wizards hang in my node2 when I gonna create a "New iSCSI Virtual Disk" from Server Manager->iSCSI option.

A picture is worth a thousand words:

I've tried several times and always happen the same. Where am I failing?

Both VMs are connected to my DC in the first VM (2012 DataCenter OS)
