I am generating random points to sample within a stratum. Data Management Tools > Feature Class > Generate Random Points This works just fine, except that I noticed the points I generated for sampling this year were exactly the same as last year. Every time I generate a new set of points, they are the same points each time.

Is there a setting that will fix this?

I am using ArcGIS Desktop 10.3.1.

    You likely need to set a seed value for the random number generator somewhere in the settings. It does not appear to be an argument in the actual tool, which is an absurd over site on ESRI's part. Commented Nov 27, 2018 at 19:41

The tool will always return the same results unless you set the Random Generator environment value. Click the Environments... button at the bottom of the tool and select the Random Numbers section. See the help page for the Random Number Generator for details.
