How do you synch up the contents of directories on two separate Win2003 servers ?

We are moving from a single Win 2003 web server to a 2 node cluster shortly.  Currently, we use FrontPage to publish content from one development web server (intenal) to one production web server (external - the public sees and uses this one).  This is easy when it's only one server in production.  But when you add a second server in production, you want the second to look exactly like the first.  All we want to do is make a directory on the second server look exactly like the same directory on the first so that when we publish to the first, we don't have to publish to the second too.  The second will take care of itself.

Is there a package that will do this ?  I thought I remembered that Microsoft had something to do this ?  I think in NT they did with "directory replication."

Looking for recommendations.

Thanks,

John
