Greetings! One of my clients is having the same problem as you two. However, they are not using Win98 on any of the machines. It's a peer-to-peer network with each client running XP Pro. Each PC has Office 2003 Basic. Each PC is also using Norton AV. So far the problem has only been with Word. The problem began a few days ago and is somewhat sporadic. Sometimes the folder will open, other times not. I did download the latest Office updates but that made no difference. I thought perhaps that the names of the folders were too long, so I tried using shorter names. That worked briefly - then back to the error. I also tried moving a particular folder that seems to be the most troublesome to a different directory. It appears to be working right now, but it doesn't tell me why I am getting the error in the first place. Any tips for fixing this problem is greatly appreciated. Thanks! buk
