Question : Avoidoing roaming profiles for all domain users on one workstation

We have a NT domain and users configured to use roaming profiles.
On a specific Workstation with a CD Writer, I would like all the users to be able to log on the domain but I don't want their roaming profiles to be downloaded at all, this in order to speed up the login.
How can I configure the NT workstation in order, not to have the roaming profiles downloaded and still log on the domain ?

Answer : Avoidoing roaming profiles for all domain users on one workstation

A solution could be replace the standard msgina.dll with a new gina wich simply doesn't load user profiles, but this is a quite expensive task...
There are two examples in the msdn of how to write a gina dll.
