Steve,

The only times app registry keys get deleted are:
1* when the application is being uninstalled
2* when someone manually deletes the key or that someone writes a script
to delete the reg key or that same someone uses the reg delete "path to
the nodename/pwd key" in the command prompt.

The reg key for TDP won't just disappear overnight and the logs won't
tell you why this happened only that something happened. I would look
into the event viewer around the time the TDP backups stopped working
and see who last logged in and whether there were any particular script
that might have affected your reg key.

Have fun hunting Steve :-)

Subject: [ADSM-L] node pwd in registry disappeared

Windows2003 Enterprise x64,  TSM 5.5.1, TDP 5.3.3.0

We had a situation where one of our SQLServer's TDP backups stopped
working on a certain day and when I investigated, I discovered that the
registry key that holds the nodename/pwd for the TDP node had
disappeared from the registry.  I cant find any tsm or Windows logs that
would point to why this happened.

Has anyone seen this behavior before, or have any ideas on how to track
down what caused this?

Thanks,
