  I wonder how you suppose that I can see this, as there doesn't seem
  to be any mention of VLANs in your earlier messages.

  Some more questions come to mind:
  - how are the VLANs separated
    (tags in a common broadcast domain, or disjoint sets of switch ports)?
  - how is traffic routed between the VLANs?
  - where is the DHCP relay located?

  Since one client behaves differently, there must be at least one
  significant characteristic (in the client, relay, server, network
  path, or the coherence between these) which is not the same.
