Changing project file locations

I'm teaching a high-school class in a networked lab with limited permissions for students.

At the suggestion of a student, we downloaded the community version of Unity for their use and installed it on several student machines. Students are not able to save assets.

Unity will only store projects and the associated folders in C:\Documents and Settings\[username]\My Documents. Any attempt to get it to store anywhere else is blocked. In our networked environment, for all users, My Documents is mapped to a file server folder as a network drive. Students only have permissions to access their network file server folders, and cannot read or write to the local hard drive.

Question 1: How can I change the default location for Projects in Unity to either the students' mapped file server folder or my lab file server?

Question 2: I installed the Unity Asset server on my classroom file/web server but the option to open the control panel is grayed out in Unity. What do I need to do to access the Unity Asset server?

For your first question, why not just browse to where you want when you create a new project? That sounds like your network is limiting the save process, not Unity.

For your second question, you need Unity Pro per seat. Which is like $1500. I don't know if the the asset server is an additional fee.

However, the asset server is so that an entire team can work on one project. I assume you are wanting to practice networking techniques. For this, you might want to just create projects and have your students follow you along as you write the server/client code.

Edit: If that doesn't work, just create a project on a personal computer and distribute it to the drives of the students. Unity can open projects by selecting the root folder. Make sure that each student plus you have a copy. Unity won't allow two users to open the same project.
