Hi All. Anyone know if the DHCP setup on ROACH 1 renews its lease? I'm woefully ignorant of all things DHCP...

If they are not doing so it would explain the symptoms we are seeing. The only cure I can think of if that is the case would be to assign permanent IP address and create static DNS entries. Also would need to configure the roach boards appropriately.
