Is thiere any way to control mac (9 or x)client form a windows server "applying policy" ? what i mean is to control it as we control ms windows client "disaple add remove , remove some option .... "restrected user"?

The only policies that will probably work would be password policies.

Most MS server policies are windows specific.

You can bind an OS X Server with a MS Server, and expand the Active Directory to have Open Directory features in it, but thats getting heavy duty. And from the measure of your question, I would say avoid that.

"The only policies that will probably work would be password policies"

am already reading about it .. but if you know anything about it plz fill me ??? thankx

You're talking about printer and file sharing. Which is not new. As for authentication, thats just binding the OS X machine to AD.

You can just have printers be IP printers, and your problem is solved.

Windows machines can access Mac files, and vice versa.
