Laptop on two different networks

[mogwai]

Is it possible to have my mum's laptop be part of two different workgroups? One when she uses the normal network socket at school and then on the other one at home when she is using wireless?

She will more than likely have full access. The only issue is that the workgroup at home and school are called something different. At home it needs to be part of the workgroup for file and printer sharing.

Would it simplify the whole process if I renamed the workgroup at home to match the school one, and changed the user account she uses at home to match the school one?
