OpenGL and ortho2d

I did a program a while back on windows 98 using openGL. I upgraded to windows 2000 and the same program (Code unchanged) ceased to work. The problem (According to VC++6) is

Gasket.obj : error LNK2001: unresolved external symbol _gluOrtho2D@32
Debug/Gasket.exe : fatal error LNK1120: 1 unresolved externals
Error executing link.exe.

It uses glut and I have put both opengl32.lib and glut32.lib in my link settings for the project. It is a simple 2d project and as I said it worked fine in windows 98. Any ideas? I would prefer not to post the code because it is awful code (It is Sierpinski Gasket using the recursive algorithm).

Thanks in advance

if you use gluOrtho2d(…) you will need to link with glu32.lib as well, you could also just use glOrtho(…)

OK, I did that and it works kind of. The background looks crap and dirty. Any ideas.
