Limitations of DHCP Option Overlays

ID: Q121006

The information in this article applies to:

Microsoft Windows NT Server versions 3.5, 4.0
Microsoft Windows NT Workstation version 4.0

Microsoft Windows NT 3.5 DHCP (Dynamic Host Configuration Protocol) Server and Client do not support option overlays to expand the DHCP packet beyond 548 bytes, but only up to 336 bytes. This is enough space for a reasonable set of options.

If a non-Microsoft DHCP server is sending the option overlays, make sure they all fit in the standard options field. If that is not possible, make sure that those used by the Microsoft clients fit in.
