Oracle Database Discussions

I have encountered an error whilst installing oracle 9.2.0.1 on a Windows 2003 Server. The error appears in the final part of the installation, when the Database Configuration Assistant is performing some work - it reaches the part where it creates the database instance - here we get the "ORA-12546: TNS Permission denied" error - this part of the installation is marked as failed - i can retry it as many times as i want but the same thing happens. If i finish the installation (even though the error has occurred) the oracle installation doesn't really work . I can't open the Database Configuration Assistant and don't really have a sysdba user. However all the services seem to be running fine (even the tns listener)

I was wondering whether it could be a problem that would be solved with the 9.2.0.3 patch - but this patch assumes that you have performed a proper working installation of 9.2.0.1, so I'm not quite convinced that the problem is related to the oracle version.

I've read other threads where the problem has been read/write privileges on some files and folders, but this shouldn't be an issue when I'm logged onto the machine as a local administrator.

The install.log files don't really provide any extra information.
