XP SP3 sends out DHCP packets with Option 43 data (including Microsoft's "Vendor Specific Information"), which Service Pack 2 (SP2) did not. However, Option 43 data is not compatible with 5200 series router's original definition, which causes the problem (as reported from a notice from Billion)
RFC2132 says: "Servers not equipped to interpret the vendor-specific information sent by a client MUST ignore it (although it may be reported)."
It seems to be a Billion's fault...not Microsoft's
