Restore or copy Share Definitions To Another Server

details a workable method of restoring shares from one server to another server.
The procedure involves restoring the old server’s system.hive to the new server
and importing the share subkey. It works. I have used it. The method assumes
that the accounts and groups exist on the new server. In
fact, the procedure only works when the old and new server are domain
controllers within the same domain. As such, they share a single SAM with the
same accounts and groups re: SIDS.

If the “old” box and the new box are member servers, once you restore the
shares, you will find that the shares have permissions granted to “unknown
accounts”. The SIDs for the accounts and groups do not match. Microsoft has
released a new (Jan 5, 2000) KB article, Q250267
which details how to copy shares from one member server to another with the ACLS

You use Resource Kit utilities getsid to copy the
SIDS from the old server, scopy to copy the files and
acls (now Unknown), and Subinacl to apply the getsid
data and make it all work. The following command can be used to print out the
acls for a file:

subinacl /verbose=1 /file c:\whateverfile.txt /display
