область перенесена с DHCP win2k3 зацепилась без проблем

Это и есть проблема, см. аналогичную тему:

Open DHCP mmc Open Command prompt: cmd Type: netsh dhcp server export C:\dhcp.txt all in command prompt and press Enter Delete ALL scope information from within the DHCP mmc Type: netsh dhcp server import C:\dhcp.txt all in command prompt and press Enter Right-click server name within DHCP mmc and choose refresh At this point I was able to view all of my Address Leases. All entries had a Name that was equal to its Client IP Address, a Lease Expiration of the time of my export, a Type of DHCP/BOOTP, and a very long Unique ID (32 characters). After performing a "Ipconfig /renew" from a workstation, the workstation's Name appeared correctly, the Type changed to just DHCP, and the Unique ID was the MAC address of the workstation.
