I don't know know do to that in SAMBA, I would like to know, if anyone knows how.
But, I known how to limit which folders will be copied to roaming profile in Samba Server and/or how to limit its size and it is not related to SAMBA, but to windows itself. It is a configuration you need to apply in each Windows XP you would limit.
It is a Windows XP administrative tool named gpedit.msc (Start/run/ and type "gpedit.msc" on text box)
On the left panel, this particular settings is in "User Configuration/Administrative Models/System/User profile". The settings itself are in the right panel.
I hope this can help.
