Regarding the Network Time Protocol (NTP), if we have a Windows XP NTP server
and the network has other Windows XP clients as well as Linux Redhat 9.0
clients, what is the process that we need to follow to be able to allow a
manual clock change on the server to be reflected on all the clients?

It's not really smart to set it up the way you have it considering the
built-in time service will poll ntp.microsoft.com or your own
preferred ntp server. A manual clock change happens by clicking the
tray icon clock and setting it by hand. If the host server already HAS
it's time service running, it will already be synched to
ntp.microsoft.com in which case your client should be pointing to it
as well, not your server. You are complicating your environment for no
good reason.

Given time, all clients should sync up with the server assuming they
are properly configured to sync from the server. Clients usually check
servers every 20 minutes to every 9 hours. I think XP Home is
once/day. A lot also depends on how much your "manual clock change"
differs from the current time on the client system. If the difference
is too big, the client may not accept the change (look in your System
Event Log). Also, the change will probably not take place
instantaneously but skew in gradually over time.

A lot of good information is presented here:

The client's clocks will be reset the next time they query the NTP
server. AFAIK (and I'm not an expert on this protocol) there's no way
for the NTP server to tell all machines that might connect to it that
its clock has been reset.
