It's a desktop app written in .Net which uses Oracle ODP.Net. The lock of the system user was found on a Win Xp Pro SP2 machine. It's worth noting that this is the first case in 200+ installations.

Me too... in fact we are pushing our customer to adopt Oracle STD and buy a dedicated Oracle server for each office (which has from 1 to 6 or 7 clients). They were used in this way because of the previous application that is going to be replaced by ours.

I haven't logs which could prove my statement, and in fact it was just an assumption based on the fact that the system password is the same in all the installations and it has never changed from our first installation up til now. We have a bunch of functions in a windows service which, periodically, uses the system user to perform database specific tasks (gather stats, unlock users, etc), but the pwd is embedded (crypted) in the c# code, so, i presume (but at this point I'm not so sure), it can't be wrong.

Unfortunately this office is assisted by an external IT service and they called us just to fix the problem, they only said me that none of them tried to connect manually as system (in sqlplus for example).

Thank you very much anyway, and sorry for my italenglish :-) I presume this matter will remain unknown.
