>I only have Nt workstation loaded along with NT Option Pack 4. So what now?

Did you install IIS from the NT4OP (not NTOP4, dammit -- that's not addressed at you, I've seen even MS screw it up)? If so, then just point Interdev at your own machine. You may need to install the FrontPage extensions from one of your VS setup disks, though -- I don't remember the exact sequence.
