I've got what may very well be an amazingly simple question (or not). Basically at the office we're using RDC and LOGMEIN-CENTRAL to manage access to computers. This allows branch offices access to internal machines. There is one machine in particular that we need to lock down and allow folks to access but give them no local permissions. Basically anyone logging in to this machine will have internet access, and the ability to grab files from that one machine alone, but absolutely no other network privileges at all (i.e. can't see other local machines, printers etc). There is no domain server, LDAP, etc -- simply XP machines in a workgroup.
So I'm wondering, how exactly do I so something even remotely similar to this? Can I simply remove something like "Client for Microsoft Networks", or does XP have some sort of Group Policy I can edit?
