Hey All,

I've been scouring the web looking for a way to change what the various
flavours of Windows send as data for DHCP client option 60. Microsoft's
documentation & tethereal show this for a w2k pro box (NIC is in a VLAN
where DHCP relay is not configured, for example only):

<snip>
Option 53: DHCP Message Type = DHCP Discover
Option 77: User Class Information (12 bytes)
Unknown Option Code: 251 (1 bytes)
Option 61: Client identifier (5 bytes)
Option 50: Requested IP Address = 169.254.32.82
Option 12: Host Name = "host"
Option 60: Vendor class identifier = "MSFT 5.0"
Option 55: Parameter Request List
</snip>

I checked the registry for both text and hex versions of "MSFT 5.0". The
MSKB refers to a couple of ways to change the user class, but does not
address the vendor class specifically. It appears this value is hardcoded
into a dll somewhere.

Is there any way to change this value?


Cheers & TIA,
