proxmox 2.3 Windows 2012 not booting reliably

[mountaindogs]

I have a Windows server 2012 running default install and exchange 2013. It simply will not boot completely anymore. Shortly after the blue window logo appears and the dotted circle swirls under it, the summary view in the web browser shows the cpu pegs at 120% for 5 minutes, then drops to 101%. It will stay at 101% for hours if I let it. It boots into safe mode with network with no issues. I can find nothing obvious in the event log. There are two other Windows 2012 servers as domain controllers that have the same symptom but after a few resets they eventually come up.

Does proxmox have any tools that can let me see inside the machine to maybe catch what process may be the culprit? Any pointers as to how to troubleshoot? Change cpu type? Increase memory or number of cpus for the vm?

Cheers

Isolated it down to Active Directory communication. While in Safe Mode I disabled the nic. Rebooted and the vm came up no issue. Rebooted again, still worked. Added new nic, removed old nic, both e1000. Had to configure new nic from powershell using new-netipaddress. Why did I change nics you might ask? The old one did not have ipv6 enabled for whatever reason and when I would try to enable ipv6 the vm would lock up. By adding the new nic, ipv6 was enabled by default.

I am asking this on proxmox because I could not isolate the issue and was looking for help. Help along the lines of maybe a tool at the proxmox commandline that could look into the vm and see what process was putting the load onto the cpu. The browser console is awesome but limited by what the guest os is displaying during boot. Since Windows doesn't really display anything I was hoping for an alternative.

AFAIK you'll need to install ssh server on windows machine in to get access from cli:
