Re: able to get dhcp from default vlan but unable to get dhcp from clients vlan.
The config is fine, probably the problem lies elsewhere. Does the DHCP server know how to find its way back to the 10.76.96.0 network?

Re: able to get dhcp from default vlan but unable to get dhcp from clients vlan.
Concur with other poster, you may need a static route in your 10.76.12.1 router to find 10.76.96.1 via 10.76.12.2

Re: able to get dhcp from default vlan but unable to get dhcp from clients vlan.
have you made a traceroute from your DHCP server to 10.76.96.1?
As your DHCP-Server has the IP 10.76.12.15 it needs to route the traffic to 10.76.96.0.
We assume it uses 10.76.12.1 as it's default gateway.
But does the router 10.76.12.1 know a route to the 10.76.96.0 subnet? If not, the server can't reach the clients in that subnet..this means the server gets the DHCP requests, and answers, but the packets are dropped at the router or somewhere else.. but the switch is configured ok.
basically the router 10.76.12.1 needs a route:
ip route 10.76.96.0 255.255.255.0 10.76.96.2

Re: able to get dhcp from default vlan but unable to get dhcp from clients vlan.
You should type that command on the switch/router that is default gateway in vlan1, probably 10.76.12.1.
