Here's the code I'm trying to synchronize. Both computers use this exact
method.
RandomNumberSeed is an integer property
///
public int RandomNumberSeed
{
get { return randomNumberSeed; }
set { randomNumberSeed = value;}
}
BreakUpRandomSeeds is a method I use for generating new random seeds later
on.
Notice I'm printing out the results as soon as they are generated. The
property is merely a placeholder for the data.
///
private void BreakUpRandomSeeds(Unit unit, int seed)
{
Random rnd = new Random(seed);
unit.a.RandomNumberSeed = rnd.Next();
unit.b.RandomNumberSeed = rnd.Next();
unit.c.RandomNumberSeed = rnd.Next();
LogFile.Log("BreakUp: " +
unit.Delta.Name + ": " +
seed + " " +
unit.a.RandomNumberSeed + " " +
unit.b.RandomNumberSeed + " " +
unit.c.RandomNumberSeed);
}
For now, I changed the code a bit. Instead of grabbing .Next(), I use
..Next(1000), which may be just random enough.
So far, I haven't seen differences on both machines. I'm worried that
whatever was causing the slight error I was seeing for the larger
numbers may once in a while cause a rounding difference with the 0 to 1000
set. So far, this hasn't been the case.
I wish I knew more about the internals of the Random class.

Can you post the code you are using that generates the output you showed?
(For both machine 1 and machine 2)

Oddity: I can't really reproduce this when I use a stand alone
application. It seems to only happen in my primary app.
