Okay.  Fortunately, we're not doing that.  "Missouri.edu" is not an AD domain.  "Col.missouri.edu" however, is.  So a dnps-caplap-4.col.missouri.edu is a computer named dnps-caplap-4 in the col.missouri.edu AD domain.

So the "first dot" assumption should work IF you take "col.missouri.edu" as the domain, rather than just "COL" (that which is between the first two dots).
