Windows 2008 AD and Exchange 2007 Problem

We have AD and Exchange 2007 running at Windows server 2008 Hyper-v. The AD and Exchange Hyper-v crash due to some disk space problem. But We manage to recover backup both VM. Now, after recover bring up both VM, Exchange seem like not able talk to AD. It show error can't find Domain Controller.

Should i remove Exchange as member for DC and rejoin back as member? How to make this work. We really need this be up as soon as possible.

First thing to check is DNS and network connectivity.
Can you ping the DC from the exchange server using the DC's FQDN?
If not, I would start getting that working.

Unjoin Exchange from AD and rejoin it to AD. Then you can restore your mailbox store into Exchange to get message back.

Has Powershell sent you back into the Stone Age?

If managing Active Directory using Windows Powershell® is making you feel like you stepped back in time, you are not alone.  For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why.

At this moment, I put both AD and Exchange running at internal network. Now after unjoin the Exchange, seem like i can't join back the AD. When ping AD and FQDN request time out. The weird thing when ping Exchange itself Internal IP address also timeout. Is it something wrong with Hyper-v Virtual NIC?
I try remove Virtual NIC and add back still the same can't ping DC at all.

I think there is something wrong with your network
Reboot the DC and exchange and then try to connect exchange back to Domain.

Let me know if you get any error message.

Thanks.
