Windows Server 2008 AD Domain Administrator Password Reset

Hi All,

I want to change the Administrator password (Domain Admin, Schema Admin, Enterprise Admin) in my environment. Because, This password has been shared to team members unknowingly.

Please Let me know, If i change the password,will that affect the any other services like Exchange,DPM etc..

Everyone is using the admin password is security breach.. thatswhy..

Thanks & Regards
