How to turn off the interpolation of pixels

Hi,
I'm rendering a 2x2 dimension texture and i need the pixels on it to not to interpolate.Due to interpolation i get one pixel on the bitmap and the rest are gone. Is there a way to turn off the interpolation when rendering to surface. I'm using RenderToSurface class and get the surface from the target texture and render it to the surface.
I'm using VS 2005, C# and Managed DirectX 9.0c.
