We have a Windows Server 2008 that is running Oracle 11g. The server was configured for terminal services for administration. This only allowed 2 people to remote to the server at a time.
Today I upgraded the terminal services so that more people can log on at once. After the upgrade, Oracle isn't working. Specifically, the website that uses the database reports ora 12514 error. Sql Developer can't connect to the database on the local machine.
All of this was working just minutes before I did the upgrade and I have searched to try to determine what to change after modifying terminal services and found very little information.
