Your network contains a server named Server1. Server1 has the DHCP server role installed and contains multiple scopes.
You restore the DHCP database and discover that the active IP address leases are not displayed. You need to ensure that all IP address leases are displayed.
What should you do?
A. Reconcile all of the scopes.
B. Run jetpack.exe dhcp.mdb temp.mdb.
C. Restart the DHCP Server service.
D. Authorize Server1.
Correct Answer: C

Correct answer(s): C
Recovery: Restoring from Backup
If the DHCP server database becomes corrupted or is lost, simple recovery is possible by replacing the server database file (Dhcp.mdb), located in the
% SystemRoot %System32Dhcp folder, with a backup copy of the same file. You can then perform a simple file copy to overwrite the current corrupted database with a backup copy of the same file.
If DHCP Manager has been used previously to enable backup, you can obtain the backup copy of the server database file located in the % SystemRoot %System32DhcpBackup folder. As an option, you can also choose to restore the Dhcp.mdb file from a tape backup or other backup media.
Before restoring the database file from backup, the DHCP service must first be stopped. Once you have copied the backup file to the % SystemRoot %
System32Dhcp folder from your preferred backup source, you can restart the DHCP service. To stop the DHCP server service, type the following at a command prompt:
net stop dhcpserver Once the DHCP service has been stopped, the following procedure can be used to safely restore a backup copy of the database from either backup media or the DHCP service backup folder.
First, move the files from your existing DHCP folder to a different folder location, such as Olddhcp. Be careful to keep the DHCP folder structure intact. For example, type the following set of commands at a command prompt to perform this step:
md c:Olddhcp move % SystemRoot % system32DHCP*.* C:Olddhcp Next, remove the corrupted server database file. This can also be done at the command prompt:
del % SystemRoot % system32DHCPDhcp.mdb
You can then copy the backup database file into the DHCP service folder. The path to be used when performing the actual copy operation varies (as shown in Table 4.15), depending on the specific server version of Windows running on the computer where the DHCP database file is being restored. http://technet.microsoft.com/en-us/library/cc958954.aspx
