Soluzioni

Se il database del server DHCP viene danneggiato o perso, è possibile ripristinarlo sostituendo il file di database del server (Dhcp.mdb), posto nella cartella %SystemRoot%\System32\Dhcp, con una copia di backup dello stesso file.

Se Gestore DHCP è stato utilizzato in precedenza per eseguire un backup, è possibile ottenere la copia di backup del file di database del server posto nella cartella %SystemRoot%\System32\Dhcp\Backup. È inoltre possibile ripristinare il file Dhcp.mdb da un backup su nastro o da altri supporti di backup.

Per eseguire queste procedure, è necessario essere un membro del gruppo Administrators oppure avere ricevuto in delega l'autorità appropriata.

Per ripristinare una copia di backup del database DHCP:

Fare clic sul pulsante Start, selezionare Tutti i programmi, Accessori, fare clic con il pulsante destro del mouse su Prompt dei comandi, quindi fare clic su Esegui come amministratore.
Digitare net stop dhcpserver, quindi premere INVIO.
Digitare md c:\olddhcp, quindi premere INVIO.
Digitare move %SystemRoot%\system32\DHCP\*.* c:\olddhcp, quindi premere INVIO.
Digitare del %SystemRoot%\system32\DHCP\Dhcp.md, quindi premere INVIO.
Digitare copy %SystemRoot%\system32\dhcp\backup\jet\new\dhcp.mdb %SystemRoot%\system32\dhcp\dhcp.mdb, quindi premere INVIO.
Digitare net start dhcpserver, quindi premere INVIO.
