I just recently realized that, with the release of Tiger, Apple has changed how Simple Users can mount network shares. In Panther (10.3), it used to be that Simple Users could mount any volume on any system over a network, as long as they had sufficient permissions. Now in Tiger, Simple Users can only mount the boot volumes of machines on the network. Meaning you cannot mount any additional volume (internal hard drive, FireWire drive, etc.) over the network. For me this was annoying, since I work in a school system and we have many G5 animation labs. All students have Simple User accounts, and we wanted to be able to mount additional volumes so they can make network shares to save their projects.
Someone recomended an application to get around this to me. It's a donationware app called SharePoints, and it does exactly what I need. I just created a group policy for Simple Users on the machine I designated to have the network shares, and I was able to mount all volumes on the system with every Simple User on the network. Thanks to 'Raven' for recomending it to me.
[robg adds: We've covered SharePoints here before. The program itself was, in fact, inspired by this hint from 2001. SharePoints lets you easily share any folder on your machine, much like you could with System 9's sharing feature.]
