Blax's questions

I have taken over all IT responsibilities for a company that is using Active Directory (2008 R2 native level) and Exchange 2010. I have come to find out that their internal Active Directory domain name is the same as an external internet domain name that they do not own. I understand that domain rename with Exchange 2010 / server 2008 r2 is not possible as far as I have read. Could someone help me to realize what other options may be available to me? They have quite a large infrastructure so moving to a new forest would be a massive job I would like to try to avoid if possible.

Thank you in advance for your help.

I have a hyper-v server that runs 5 virtual machines. I believe the physical box rebooted last night which is usually not a problem but this morning one of the virual machines is stuck at "restoring 0%". I have rebooted the physical machine and same thing, 4 virtual machines come up fine the 5th gets stuck at "restoring 0%". I right-clicked the VM in hyper-v manager and selected "Cancel restore" and nothing happens. I was able to copy the VHD to another hyper-v box and light it up there so I know the VHD is good.

Any ideas on what to look at next? If I can I would like to just dump the saved state and move on, or if there is a better way to handle it I'm all ears.

TIA!!
