If you do a little searching in this group, I believe you'll find messages
indicating where to find the .MSI file. With previous versions of the
installer.exe, I was able to use the network install switch to expand the
file and get the .MSI file. However, I believe I looked into doing this with
the .701 version and didn't find that switch listed when I ran the executable.
Microsoft (and I) recommend that you NOT do this with the beta1 product.
This beta is not designed for this usage, and may create problems for
you--for example, it will raise user dialogs for any administrative scripts
you may run, or software installs you may do via AD.
I believe this kind of install is possible, however it isn't trivially
simple--some have succeeded, others not.
