oracle issue
Yes, sure ! You must be the local admin of this computer, and not a domain user.
Moreover, I'm afraid you cannot install it in a domain, maybe you should (just for testing purposes) try to install a standalone Windows system and try installing Oracle 10g on it.
You know, a RDBMS database server must be installed on a server system. You can cheat, installing it on a standalone Windows system, the standalone system emulating a server. But I'm even not sure you can install it on a client machine. Oracle server is traditionally installed on server systems, and Oracle client is installed on client system.
Please, keep us informed, if you were successful loggin on your own system as localsystem administrator, and if you were then able to correctly install Oracle.
If not, I strongly suggest you to restart everything from scratch (even on an old machine) just for learning purposes. After installing on a brand new Windows standalone system, you will feel more confident for installing it on your client system.
