After the name of a Tivoli® Storage Manager server is changed, the generated password on Windows backup-archive clients is not usable. The password is generated on backup-archive clients that use "passwordaccess generate". The generated password is not usable because the generated password is stored in the Windows registry in a key that contains the server name, such as the following: HKLM\SOFTWARE\IBM\ADSM\CurrentVersion\BackupClient\Nodes\<NODENAME> \<SERVERNAME>\Password If the backup-archive client is not able to authenticate with the Tivoli Storage Manager server then scheduled operations for that client will not run.
Until the password is reset, the Windows backup-archive clients that use "passwordaccess generate" are unable to authenticate with the Tivoli Storage Manager server.
Either change the Tivoli Storage Manager server name back to the original name, or reset the password on the server using the UPDATE NODE command to a known password and then use dsm, dsmc, or dsmcutil to manually set the password on all Windows backup-archive clients that use "passwordaccess generate".
