I think I have found out what the problem is but I am having a difficult time trying to solve it. I checked in services, all the oracle service are supposed to start automatically, but none of them started. So I clicked on them and clicked on the START button but it returned this error message:
could not start the oracleservice PROD on DDDDDD
Error 003: The system cannot find the path specified.

Note: PROD is the name of the service and DDDDD is the name of the computer(system)

CAn any body help with the spaecifics?
