TDI legacy driver installation on Win2K

My objective is to load a TDI legacy driver above tcpip and below netbt.
advice on the best method is appreciated. I have tried the following

  1. Currently, I am using a reg file that creates an
    HKLM\system\CCS\services\mydriver key. This key contains a value Group
    to PNP_TDI and a value Tag set to 5. Subsequently, this reg file
    overwrites HKLM\system\CCS\services\netbt\Tag to 6.

The Win2K states that all drivers must have an inf file, so my plan is
write a custom installer that performs the task of importing the reg
The Win2K installations I have observed always have
HKLM\system\CCS\services\tcpip\Tag set to 4 and
HKLM\system\CCS\serivces\netbt\Tag set to 5. Just in case this is not
true, my installer checks for other drivers in the PNP_TDI group, sets
mydriver\Tag to the value of tcpip\Tag + 1, and then adjusts subsequent
xxxx\Tag settings as appropriate.

I have 3 concerns with this approach:
a. Not a Microsoft standard method.
b. Tag may not always be available.
c. On reboot, Win2K creates a root enumerator key: LEGACY_MYDRIVER. Upon

uninstall, I do not want to leave any traces of my driver. However, I
have not found a way to delete this key.

  1. Using the Oney Ioctl sample inf as a template, I tried installing my
    using the install command in the Win2K DDK. This certainly loads my
    but way to early. I experimented with DependOnService, Tag, and
    LoadOrderGroup to load my driver at the appropriate time, but the PnP
    manager ignores these settings. I think this is because the Oney sample
    includes a hardware ID which indicates to the PnP manager to load my
    while walking the device tree which occurs immediately after the boot
    drivers are loaded.

  2. Install my driver as a network filter driver by using the snetcfg
    from the Win2K DDK. This did not seem to work. Additionally, I tried
    the filtject Oney dll to set
    HKLM\system\CCS\Enum\Root\LEGACY_TCPIP\UpperFilters, but this did not
    to work either.

Thanks in advance,
