I can"t believe I missed this one being a GeForce Ti4400 owner (overclocked to Ti4600 speeds) :ninja:
Guru3D have a 43.03 driver listed for Windows 2000/XP but also for Win9x/Me posted on 19th of March 2003 and the .inf file shows 03/03/2003 as the date. These are for all nVIDIA cards and not endorsed by the nvidia web site, so they carry no WHQL (or candidate) signature. Recent reports have been good with the newer driver version increments showing performance gains rather than losses so they might well be worth checking out.
As always only use these if you know what your doing :P
