ODP.NET

HI
I have downloaded the ODB.net software and installed the software.
MY OS : Windows 2000
My DB : Oracle 9i Release 1

While installation, a wizard asked me to stop my local machines database and TNS Service, HTTP service etc... SO i have stopped all oracle services, and again i started the setup. it went through fine. While finishing the installation the installation wizard asked me configure the net service. During this process i selected the option to manually setup the net service. And wizard took me to window where by it asked netservice name i have provided my local machines net service name. and host name to be local machines name but it failed to connect with the server, so alternatively i gave another net service which is available in my office network. Finally it succeded the installation.
And now i tried to restart my local database service name and while starting the service it gives me the following error message.

Window Name : ORACLE.EXE ENTRY POINT NOT FOUND
Window Description : The Procedure Entry Point kdrgtl could not be located in the dynamic link library OraCommon9.dll

and after this message another message is poping up

Window Description : " Could not start the OracleServiceVenkat service in the local computer
Error Number 1053 : The service did not respond to the start or control request in a timely fashion

Could any one tell me how to access my local database.
