First of all, you already have an answer at OpenGL.org Discussion & Help Forums.

Secondly, 3D textures are not implemented in the GeForce2 series. At best you will have them in software, which is EXTREMELY slow (believe me, I''ve tried, software 3D textures are 50x slower than hardware 3D textures).

Thirdly, double posting is BAD. Expect one of your threads to be closed or deleten very soon.
