Resetting the password for the Domain Admin Account for CCS 10.5

We are putting a process together for resetting the password for the Domain Admin Account for CCS 10.5 every 90 days.  I know that ID/Password is tied into various places withing CCS and the RMS console.  Does anyone have a reference or article that explains where we would have to reset the password for the ID within the two applications?  

Thank you!
