Are specular shaders supported in WebPlayer?

My apologies for posting redundantly. I will try again and be more clear and careful!

• am running Windows 7 Professional (64bit).

• am using Maya 2009 to create all assets. In Maya I created Lambert shaders for all objects. Exported from Maya as .FBX file.

• use Photoshop CS5 to make textures (.jpegs).

• am using Unity 3.5.3f3

In Unity, I changed several shaders to Specular. When I play the level inside the editor, the specular shaders work fine. But when I Build the level for WebPlayer the specular shaders seem to switch back to diffuse.
