I'm thinking its a windows 2000 permissions problem.. I ran into a similar problem when trying to use it on my school's computer.. neither rcxcc nor the mindstorms software could see it. What type of IR tower are you using? I tried with the 9-pin serial one
XP doesn't have this problem, neither does win98se
Also know that I'm fairly certain you can only use the mindstorms software or robolab to program the actual model to use. And from what I've seen, robolab is more powerfull
