Have been having a random problem with oncaommand. Despite saving my username and passowrd, after a while ity will stop saving it and show my logon name as being “NULL”. It appears this stems from an encryption key that oncommand uses. From what I gather this is corrupt in someway or oncommand can’t use it. It’s stored (on my win7 machine) in c:\users\%username%\netapp\systemmanager. Delete the three files that are in there (the key, the config and a backup) and you should be good to go next time you open it.
