Although the M$ DHCP Server does not allow you to synchronize the reserved IP(s) with other DHCP servers, but If you want, you can do it with a small trick:
1. Export the dhcp config of the master server by the command (in the command prompt windows):
netsh dhcp server \\master-server-name scope 220.127.116.11 > C:\master.cfg
The config file are something like this:
2. Creat config file (subserver.cfg) for other servers from the dumbed file above using python script:
+ Open the master.cfg file and extract the Reserved IP part of the configuration.
+ Replace the master-server-name part with subsever-name from the content.
+ Create a new file (subserver.cfg) with the new content.
3. Execute the created config file for the sub-servers:
netsh exec C:\subserver.cfg
In addition, you can make a batch file and create a task schedule in the master server to execute the batch file everyday (or even every hour) to synchronize the reserved IP(s) setting between DHCP servers.
netsh dhcp server \\master-server-name dump > C:\master_fullbackup.cfg
netsh dhcp server \\sub-server-name dump > C:\sub_fullbackup.cfg
netsh dhcp server \\master-server-name scope 18.104.22.168 dump > C:\master.cfg
netsh exec C:\sub.cfg
MASTER_PATH = 'C:\\master.cfg'
SUB_PATH = 'C:\\sub.cfg'
def create_ri_cfg(master_cfg_path, sub_cfg_path):
fa = open(master_cfg_path, 'rb')
tmp = ''
while 'ReservedIp' not in tmp:
tmp = tmp + fa.readline()
ria_cfg = ''
while 'ReservedIp' not in ria_cfg:
ria_cfg = ria_cfg + fa.readline()
rib_cfg = ria_cfg.replace('MASTER-SERVER-NAME', 'SUB-SERVER-NAME')
fb = open(sub_cfg_path, 'wb')
