DHCP
Hello friends,,
My scenario is this
i have two domains(old and new).as of now iam in process of transferring all roles and data to the new domain. all r fine ok...good
but the problem i face is with dhcp.i exported the conf of dhcp from old server and put it on a win 2003 server in the new domain.i assigned the new gateway & new dhcp and changed the dns domain name on the dhcp in new server.i authorize the new dhcp server and unauthorised the old one...but the clients are not getting ip address from the new dhcp server .....
OK tried a lot of things
This is my situation now friends
The wireless clients are getting IP from the new dhcp server
Ip details for wireless network
10.2.32.1 to 10.2.32.254
subnet mask is 255.255.255.0
Default gateway in the new dhcp is 10.2.32.21
Dns is 10.2.32.20
As for the Lan Clients they are not getting IP from the new DHCP Server
IP details for lan clients:
10.2.34.1 to 10.2.34.254
subnet 255.255.255.0
gateway in the new dhcp is 10.2.32.21
dns is 10.2.32.20
Even when i assign static ip i get a message showing,the default gateway is not on the same segment that is defined by the ip address and the subnet mask.do you want to save this configuration??
After that i get a warning also
please help me guys..
thanks in advance

The gateway on LAN side should start with 10.2.34.* (not 10.2.32.*).
The adress should be probably the LAN IP of your router.
ASKER
OK...The gateway i use 10.2.32.21 is the TMG Server
Do u have router and VLAN configuration ?
So if you have router and VLAN then
VLAN1 - Server Vlan - All Servers including DHCP and DNS Server
VLAN2 - Wifi VLAN
VLAN3 - LAN Vlan
No you should have static route on router so VLAN2 and VLAN3 can communicate with VLAN1
Also you can try route add for 10.1.34.* subnet

It seems that "10.2.32.21" is it's wireless IP. It will probably have a different IP for LAN interface (starting with 10.2.34.*).

Dear Azeem Patel
I have vlans configured
10.2.10.0-admin
10.2.20.0-IT
10.2.30-0-Student
10.2.32.0-Server vlan
10.2.34.0-main area
10.2.40.0-workshop vlan

10.2.30-0-Student
10.2.32.0-Server vlan
10.2.34.0-main area
10.2.40.0-workshop vlan
or change your subnet mask 255.255.0.0 in both segments
ASKER
Tried...nothing happening!!!
could any one of u friends help me by a teamviewer session..pls...

since WIFI devices are on same VLAN of Server VLAN hence they are able to get IP address.
I am sure there some routing to bee added on other VLAN.
On other VLAN add routing of GW for 10.1.32.21

Yes..i do have ip helper on my router...
i changed it from the old dhcp address to the new dhcp address...
i changed it from the old dhcp address to the new dhcp address...
shark the dhcp server
see if dhcp requests from the other networks are hitting the server
does your dhcp server know the routes for your other subnets?
what happens when you ping from subnet to dhcp server?

Ok First of all thanks to all you friends...
Now i figured out something...
The dhcp works with the old DNS(10.2.32.11) address when i assign static ip on clients even if the gateway is 10.2.32.21(tmg),and they are able to access internet
But when i change the DNS to new server(10.2.32.20) the clients are not able to connect.....
