Accessing network, bypassing logon with XP??

[Guest]

At our office we have a Microsoft Windows Network, our file server is a Mac
OS X server, on this server we have a 'workgroup manager' piece of software
which details usernames, passwords and file access restrictions.
We now have some mobile laptops connecting to our network, they also connect
to the server and access the files.
However, the laptop users don't appear to be loggin in to the network when
they turn their machines on and i think that instead of them using their
previously created username, password(and therefore file access rules) they
now bypass these and are merely acting as a guest user.
This is not a job which needs to be fixed on the 'workgroup manager'
software is it? I think its mre to do with the way in which they are trying
to connect. How can i sort this problem, any ideas -they are both using
Windows XP Pro.

Many Thanks.
