TDI Client- Testing Partial Indication Logic on W2K

I am seeking insight / advise in testing my TDI Client under Win2000 in
terms of partial indications. Do anyone know of a method/tool/ registry
trick that would enable (at least statistically large percentage) the
partial indication in TCP/IP stack of Win2000 so that I can stress
test/validate the logic I have for the TDI Client Partial indications.

Thanks for any input,
