OK- It sounds like maybe you are using the wrong fingering, or by "high D" you mean the 4th note on the staff? Or are you talking altissimo D?

If it sits on top of the second ledgar line above the staff...
Try playing a chromatic scale starting at "B", slurring first. Don't move to the next note until you have a good solid tone. Pay attention to what your tongue and throat are doing as you go up the scale. Your embochure may be relaxed too much.
When you get to high "C#", hold it, try to hear the next chromatic note in your head ("D"), and then go for it. Just blow! If you hit it, hold it as long as you can. If not, try again.
Do this a few times, then start trying to tongue up the scale in the same manner. You may crack the "D", but make sure you are putting air through the horn and your embochure is good and tight (but not pinching). Just keep trying. When you can play it this way, try just popping it out! It takes some work, but don't be discouraged.

If it is the 4th line on the staff:
You need to tighten your embochure, but be careful not to pinch. And make sure you are putting air into that horn! Play too loud... you can always back off after you learn to get the note out and learn control. But for now, blast it. If you can, start on a "G" (top of the staff) and work your way down chromatically in the same manner described above. Once you can play down to the "D", try slurring slowly back and forth between "C#" and "D"... sometimes the break can be weird. Just take your time.
If you play slow for 10 minutes, it will be better than you panicking and rushing... you could spend an hour panicking and not get as much work done as 10 slow minutes.

Now if it is the altissimo D:
Sorry man! Every sax player I know plays altissimo differently, and you just need to figure out what works for you! Some guys pinch, and some open up... personally, I open my throat like I am yawning, but position my tongue like I am saying "EEEE"... and again, just put some air behind it!

Good Luck!

OH- If it's a fingering issue, here is a link to a fingering chart:

EDIT: Have you checked your octave key? You can email me if you want and I'll walk you through any of this stuff.

I agree with the above answer, you might be using the wrong fingering. However it also may be problem with your alto. Your register key might not be working properly, so if i were you i would get that checked out. You might also consider getting a new mouthpiece. In my opinion a C Star is the best mouth piece you can get without going to France or whatever. Anyways, good luck.
