Edit 2: I don't have SP2 installed, do I have to install it in order to let other people access my computer? (Because I've never had problems with this when SP2 was installed)
You shouldn't need SP2, however I would recommend installing it as it might help -- but even if it doesn't help, it's still a good idea to have it

accountname and Security-IDs.
Hrm.. Could these two words have any other translation? I'd like to know why the cacls command is failing outright.
It would help alot if you could do the following on all of the computers, labeling them appropriately (ie: Working Computer = W1, unworking computer(s) = N1, N2, N3 etc..).
