Hi All,
I am working around with server 2008 for quite a while and facing a problem as below,
1.DHCP reservation error
Server Ip:192.168.0.254 (configured as DNS server for local use only with AD & DHCP)
DHCP scope: 192.168.0.100 to 192.168.0.200 excluded 192.168.0.100 to 192.168.0.110
earlier the same scope was 192.168.0.10 to 192.168.0.100. I was facing a error when I make a IP reservation against a MAC number error was " The unique identifier may not be correct do you want to use the identifier anyway" when I click yes "DHCP server received a message from a client that is not valid" and by this error I am not able to make any reservations now against MAC numbers.
The same error was also on the earlier scope and that's why changed to a new scope but did not work. Any solutions will me much appreciated
2.DNS fine tuning.
I have an open DNS account on which my WAN IP number is configured to do a content filtering. I have two LAN ports with the below IP number
Local : 192.168.0.254 ( configured with no gateway and DNS as loopback (127.0.0.1)
ISP: 192.168.0.253 (with ISP gateway and DNS as loop back adapter & open DNS)
I have did a content filtering and things are working fine. But I got to open up some machines out of this content filtering and when I try to give the IP number in this below fashion.
192.168.0.115
255.255.255.0
192.168.0.1
DNS
192.168.0.254
ISP DNS to avoid filtering
I find that 192.168.0.254 does the resolving and things are still filtered as per the schedule. Is there a way where we can configure 192.168.0.254 (Local DNS server) to stop resolving web requests and only cater to resolving local names for connectivity.
I do know its too long but solutions for the same will be help me out to solve it. Thanks in advance.
Regards,
Vaschell
