Can I build a mac server in windows Client environment ?

I have Windows 2003 server and want to make a move, So, I prefer to move to Mac OS X Server than Windows 2008.

All the workstations are Windows 7 & XP.

So, can Mac OS X Server apply its polices to those kind of windows?

Roles: Active Directory, DNS, DHCP (IPv4).

Permissions: HDD is NTFS to have more security and to apply folder permissions for the users. I will have external network storage, so, I do not think this will be a factor affecting my issue.

So, I don't have lots of services which can be complicated.

So, Can I make the move to Mac OS X Server?

Thanks,

Boudy,
