Troubleshooting DHCP Clients The most common DHCP client problem is a failure to obtain an IP address or other configuration parameters from the DHCP server during startup. If you cannot change the primary IP address assigned on the DHCP server's network adapter card, use superscopes to effect scope migration for DHCP clients on your network. Also adding to Jsree's comments i would like to say that using an IP address outside the address assignment pool for static bindings would be ideal solution in your case as The static binding is not seen becasue a lease (dynamic) already exists for that IP address on SRX and since it has not expired and neither manually cleared, the static binding

No you're right you don't need ip-helper on that interface.But still your DHCP server got a default gateway to 192.168.1.1 for vlan2.But when you check the conf on your router at Because both services listen for and respond to BOOTP and DHCP messages sent using UDP ports 67 and 68, neither service works reliably if both are installed on the same computer. i know i am making a silly mistake somewhere so i am attaching the pkt tracer file along.Also the switches are also assigned ip addresses from 192.168.1.2 - 1.8.

In the scope, make sure that the subnet mask is correct for the remote subnet. If you use DHCP servers to automatically configure the TCP/IP settings for workstations in your organization, a DHCP failure can lead to a major disruption in service. Thanks!! In most cases, these failures are related to simple communications problems between the DHCP server andthe workstations that are trying to lease addresses.
In some larger networks, disabling this feature might be desirable for network administration.
