Hi KM,
Thank you for your reply. Yes, I'm talking about the RAM disk with Remote
Boot Manager, and I'd like to change the computer name without a reboot.
Since System Cloning assigns a random computer name and our applications are
based on computer name, I have to specify computer name for each cloned XPe.
We've already used the same way to set computer name on Windows NT Embedded
(no cloning, just a same image for different computers), and it worked fine
on NT embedded. Now, we're going to use XPe for new projects.
It seems there is no way to set computer name in XPe, that's fair because
XPe doesn't know how many computers will use the same image. But I guess XPe
should give chance to user to specify their own computer names with, for
example, Remote Boot Manager or a batch file.
