Inside Buffer

Hi everyone,
I'm using 9.2 SP6.
I have a a fairly complex lakes feature class (shown in attached picture).  I am trying to create a buffer 20 meters inside each feature and none of the methods seems to be working.
The buffer tool with a negative distance produces some kind of error before the process can be completed.
The buffer wizard tool produces the result shown in brown in the other attached image.  First of all it's the blue area that I want to keep, so I would have to add the extra erase step, and second, it completely ignored the more complicated and larger polygon on top.
I used ArcMap advanced settings utility to change the buffer wizard method to "feature optimized coordinate system" which produced the same results.

Does anyone know how, using a script, tool, or anything, how to create a buffer inside a polygon, keeping in mind that this process will have to be run MANY times.
