Program installs for local machine

I’ve just setup my first XP Pro system on a 2000 Network. up til now I’ve been using 98Se. I’ve installed Quickbooks on the machine as the N/W admin and as the local user, but when I log onto the network as the network user It will not run. It only will run when logged on localy. I know this has to do with porfiles and active directory, but I’m new to this. How do I get it to run both locally and on the N/W?
