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 :-) BERTAUT TCHUISE Storage Support Administrator Legg Mason Technology Services *410-580-7032 btchu...@leggmason.com -----Original Message----- From: ADSM: Dist Stor Manager [mailto:ads...@vm.marist.edu] On Behalf Of Schaub, Steve Sent: Tuesday, July 28, 2009 10:59 AM To: ADSM-L@VM.MARIST.EDU 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?
