Mac system mounting Windows Drives

[woodsa]

We have a mac system that intergrates with our Domain controller in a sence that it uses the logon credentials for students to access the macs and thats all it should do. However it keeps mounting their H Drive which is there persona area and then seems to fill it up with program settings etc. Given the students only have 250mb is there a way of stopping it or blocking the macs mounting the drives. Thanks

You want to enable 'Force local home directory on startup disk' ticked in the directory utility to stop that happening.
