DHCP Reservation Server 2008

-

i modified mac address on existing reservation due computer swap out. problem is, server doesn't assign ip computer anymore. never issue on previous computer. have now, deleted reservation , made new one, still same. missing? client computer win7. have done ipconfig/release/renew no  success.

hi,

according description, understanding client can’t obtain ip address corresponding mac address dhcp reservation. , reserved ip address assigned mac address has swapped out. recreate new reservation dose’s work.

just 1 specific ip address used reservation has problem？

in general, client has ip address , use ipconfig /renew, try renew current ip lease, instead of asking new ip address. may try deny ip address （the client currently used） on dhcp server， , use ipconfig /release and ipconfig /renew  to force client obtain new ip address. check see if the reservation will work.

besides, may export dhcp configuration file , confirm reservation configuration. open cmd , type:
netsh dhcp server [ ipaddress  ] dump >[pathandfilename]

for example, dumps configuration of dhcp server ip address 192.168.0.1 file named dhcpcfg.dmp at location c:\dhcp\ on local computer using command line below:
netsh dhcp server 192.168.0.1 dump > c:\dhcp\dhcpcfg.dmp

open dhcpcfg.dmp notepad, click edit – find, search key word “reservedip”, check see if reservation configured correctly. 

best regards,
eve wang
