Server 2008 R2 stalls During start-up

[Jonny11b]

Virtual Box Version: 3.1.0
Host OS: Windows 7 Ultimate x64 (build 7600)
Guest OS: Windows Server 2008 R2 x64 (build 7600)

Symptom: Windows server freezes during boot and 100% the cores assigned to the virtual machine.

Explanation/Replication: I set up the guest machines in the environment, installed from a TechNet ISO. Configured the guest additions, installed updates, configured the Bridaged adapters and assigned static IPs from the Test network. Configured 3 in this manner, 2 are having the problem. On the ones that are currently having the problem, the following roles were installed:
1. AD DS
2. DNS
3. File Services

Safe mode boots to the desktop, and I can retirve error log information. However I'm not sure what I'm looking for in the application logs. I can see some errors about domain replication not happening, also some errors regaurding DCOM. I don't konw where to begin, which is why I'm here. Help, Please?

Remove hyper-v, deinstall it.

Maybe I don't understand. Hyper-V is not install on any machine. Only AD DS, DNS, and File Services, are install currently on the guest machines.
