Question : After Acronis restore of Windows Server 2003 Domain Controller to new box, Exchange server cannot see Domain Controller

I performed an Acronis True Image Echo Enterprise Server with Universal Restore of my Windows Server 2003 Domain Controller onto a new box.   I was able to get into windows, check logs, check DNS, AD, etc.  Everything seems to be working.   I unplugged the network cable from my old DC, and plugged it into the new restored box.   Everything except exchange (hosted on another box) seems to be working.   Users are able to login to their workstations and autenticate against AD on the new DC, VPN works etc.   However the Exchange box stops working.   A review of the logs shows that it is unable to reach AD on the new DC.   If I swap the network cable back to the old DC, everything begins working with exchange again.   I could use some help figuring this issue out.  Why would the exchange server have issues seeing the DC when everything else works even when connecting from other systems?

thanks in advance  

Answer : After Acronis restore of Windows Server 2003 Domain Controller to new box, Exchange server cannot see Domain Controller

I ended up purchasing a Microsoft Support incident.  They came in and had to repair AD using ADSIedit and Regedit.  We forced and Authoritative Restore of AD between the two DC's.  This fixed the problems.  I was then able to DCPROMO demote SBS after transfering the FSMO roles to Windows Server 2008 DC.   Worked out well.

thanks for all the help guys.
