How to reset the SAP* and DDIC password in MSSQL environment

Question:
Dear All,
We have forgotten the passwords for both SAP* and DDIC for one of the old client.
Anybody can help me out how to reset the password for SAP* and DDIC from databasepoint of view.
Right now we are using MSSQL Server 2000.
