Thanks for your reply 'seepy83'.
I am aware of how to set the Workgroup the same to enable file, printer and resource sharing.
However, I would like to know how the operating system is setup on computers which automatically present a logon prompt when the computer has booted up?
Thanks 'dave_the_nerd' - I think it's clear now.
So when you select the 'domain' option and enter the domain, the administration/user login prompt should appear?
Does this also cause the prompt to appear when the computer boots up each time?
What determines centrally managed user disk space etc.?
'seepy83' what I meant by centrally managed disk space is where the amount of disk quota is managed by the system administrator and the user does not store their data locally but on a server somewhere.
