Migrate users

[ac]

I am trying to migrate my users from one AD with exchange
2003 to another AD with echange. the problem is that i
want to do it all on the same server.

is there a way to export users from an active directory,
store them somewhere while I rebuild my AD and then
restore them?

thanks

What is your overall goal or reason for doing this?
Using a system state backup is obviously the easiest but if you are
reinstalling to get past a problem it will most likely bring back the
problem.
You could look into using ldifde which will export AD objects to a TXT file
and then you can reimport them. During this transition you will loose some
information like user passwords and most likely computers secure channel.

The other option I would consider is taking any machine that could run
Windows 2003 and make it a DC temporarly, while you rebuild the original
one. Of course you will need to make adjustments to DNS and move the FSMO
roles if you dont do a graceful dcpromo demotion.
