Hi Ken,
If you are on BusinessObjects XI Release 2, the following steps might work.
1. Open the Crystal Configuration Manager (CCM).
2. Stop the Central Management Server (CMS).
3. Open the CMS database administrator application (for example: SQL server enterprise manager if you are using MS SQL2000).
4. Run the following SQL statement on the CMS database.
SELECT * FROM CMS_InfoObjects5 WHERE (ObjectID = 12)
5. Delete the record that is returned.
6. Restart the CMS server from the CCM. This will recreate the administrator account with a blank password.
7. Log on to the Central Management Console (CMC) using Administrator as a user name and a blank password.
8. Now you can set the password for the Administrator account by navigating to Home -> Users -> Administrator. Once you type the password you can also check the option "Password never expires" and then click "Update"
This info is taken from this sap thread. Read it fully for more details.---> Problems with password in CMC
Thanks,
Georgy
