How was this network set up.
I am in an office that is using windows XP professional as a ‘file server’.
Unfortunately I can’t access it directly, I don’t know the username or password of an account on the PC.
There is no domain in this network environment.
Thing is... there are three different workgroups: students, teachers & admin
Everyone, and I mean everyone, can access the share independently of the workgroup they belong to and there is no prompting for a username and password.
What I would like to know, is how did they set that up? I always believed you had to be on the same workgroup and even then, you had to know the username and password of an account on the PC.
My manager would like to know how to restrict the share to just the teacher and admin workgroups and to require authentication. But he won’t give me the username and password to access the ‘server.’ I am more interested to know how to set up a share (albeit unsafe) in the first place.

It is difficult to know what is set up with too little information.
It is possible to set up a share folder or drive and type in the user name "Everyone" (no quotes) and give it limited or even unlimited access and Windows reads everyone as literally that, everyone. Not safe and not recommended though it is possible that this is how it was set up.

You have to be a little bit crazy to keep you from going insane.

Your best bet is to segregate by using different subnets.

From the looks of it you'll need two separate subnets. One for "teacher & admins" and anybody who doesn't require access to the shared resources would be in the other (student) group

Workgroups do not provide separation, segregation or security. Especially not if all 3 different workgroups are still on the same subnet. If you can't afford a "Small Business Server" to use to create a domain (recommended) then you'll want to segregate using subnets and/or VLAN's if you have a layer 2 capable switch. You would also need at least two SOHO Routers.

The following is assuming the point is to provide all 3 groups internet access and can't afford an L2 switch or Windows SBS to create a domain.

You would want something like:

Router 1
Connected to the internet
This is for students and allows internet access only

Router 2
Connected to Router 1
File server resides here along with admin/teachers
This gives access to internal resources AND the internet but the students can't access this network.

I wouldn't bother with using different workgroup names, it's meaningless anyhow.

If you click on my name above, click on "How-to Guides" and have a look at my guide on adding a second router you'll get basic instructions no how to set this up. You'll want the version wherein you interconnect the two routers LAN port to WAN port and use separate subnets.

It matters not how straight the gate,
How charged with punishments the scroll,
I am the master of my fate;
I am the captain of my soul.
