如果 DHCP 伺服器資料庫已損毀或遺失,可以將位於 %SystemRoot%\System32\Dhcp 資料夾的伺服器資料庫檔案 (Dhcp.mdb) 取代成相同檔案的備份複本,以便進行復原。
若先前使用 DHCP 管理員來執行備份,您就可以取得位於 %SystemRoot%\System32\Dhcp\Backup 資料夾之伺服器資料庫檔案的備份複本。您也可以從磁帶備份或其他備份媒體還原 Dhcp.mdb 檔案。
若要執行這些程序,您必須是 Administrators 群組成員或是已經委派您適當的權限。
若要還原 DHCP 資料庫的備份複本:
依序按一下 [開始]、[所有程式]、[附屬應用程式],再以滑鼠右鍵按一下 [命令提示字元],然後按一下 [以系統管理員身分執行]。
輸入下列 net stop dhcpserver,然後按 ENTER。
輸入 md c:\olddhcp,然後按 ENTER。
輸入 move %SystemRoot%\system32\DHCP\*.* c:\olddhcp,然後按 ENTER。
輸入 del %SystemRoot%\system32\DHCP\Dhcp.md,然後按 ENTER。
輸入 copy %SystemRoot%\system32\dhcp\backup\jet\new\dhcp.mdb %SystemRoot%\system32\dhcp\dhcp.mdb,然後按 ENTER。
輸入 net start dhcpserver,然後按 ENTER。
