Joining feature classes without a common attribute

[MeganTymrak]

I have a point feature class and a polygon feature class and I want to join the ID from the polygon feature class to the points within them.  For example, one polygon's ID is 100 and I want to figure out all the points that are within the 100 boundary and add that ID to the point table. 

I'm sure this is a relatively easy function so a quick note back would be appreciated.  Need more information?  Let me know. 

Thanks in advance for the assistance.

This is a classic overlay problem.  Use the Identity tool.  You need an ArcGIS license for this.  If you only have an ArcView license, use the Spatial Join tool.

Thank you.  That is exactly what I needed to know.
