I can't get the database to start from within DBA Studio. The TNS listener seems to configured and responding OK, but when I try to open the database, it won't even get beyond starting. I did try just starting the database, and that won't work either. I made sure all the services are started...the local SYSTEM account is associated with all the services, and the SYSTEM account does have Full Control over the c:\oracle directory.

This db is at a client site which was working when I last left it back in May. However, at this site, they have security policies that repropogate to a server when it starts up, and this machine was off when I got there. So, they turned it on, and Oracle didn't work. So, that's why we're thinking that the security settings are what is causing the problem (since no other changes have been made to that box that anyone is aware of). Can anyone tell me how permissions need to be set to get Oracle to run?
