Win98 Hangs when saving

I’ve got 30 PC’s on a small network running off a Win2k server and system policies. These PC’s are used in a Primary School environment and because of this, when it’s time to save files, the kids have to be instructed on how to do it. The problem is, as everyone hits the save button more or less at the same time, the PC’s take ages (up to 10 mins) to save or just hang altogether. This scenario will not change but I have to stop the PC’s from hanging when the ‘save’ action is performed.
