    Here you have only few suggestions:

    1. Update your machines regulary.
    2. Use antivirus and antispyware programs and update them regulary.
    3. Do not make domain users local admins.
    4. Implement password policy, minimum 8 characters, complex passwords and force users to change them at least every 90 days.
    5. Enable account lockout to prevent dictionary or brute force attacks.
    6. Eliminate all protocols that allow username and password to be sent in clear text (POP, SMTP, IMAP, HTTP).
    7. Use group policy to lockdown users machines

    disbaling D$ and user to change the password every 30 days can be set in the default domain policy.
    Why do you want to make sure local admins on PC's unless its a must.

    Because users can use the local admin password to login to another machine

    If you really want the users to be  local admins on all the machines then use groups policy.This way you would have better administration.
