When you get a chance, is it possible you could reply with the firmware version, and a copy of the current configuration (please, remember to remove any information that may be sensitive to the organization)? I will be happy to review it for you, but this may be something that we will need to run DHCP debugs or a packet capture to diagnose. However, hopefully, the configuration will point us in the right direction.
Please, do not hesitate to reply with any additional questions or information.
