MSDAORA provider stopped working

My problem is that the MSDAORA provider within my SQL Server has stopped working.  When trying to connect I get the following error message:

Cannot initialize the data source object of OLE DB provider "MSDAORA" for linked server.
OLE DB provider "MSDAORA" for linked server "WB_PWBRPR" returned message "Oracle client and networking components were not found.

SQL Server 2005 installed on windows server 2003.  Oracle 9.2 network client installed.  

I have a stored procedure that is using the OPENQUERY method that is pulling data from the linked server connected through the MSDAORA provider.  Up until a week ago this procedure was working fine.  Now I am getting the error above in the procedure and when I try to test the connection in SSMS.  

The same server is also running SSIS packages that pull data on a scheduled basis from the same oracle datasource.  In Visual Studio the OLE connection to the same datasource connects without and issue and the SSIS packages run without an issue.  That leads me to believe that the oracle network client is not the issue, but the MSDAORA provider in SQL Server has been changed in some way.  

I need help on how to fix the MSDAORA provider in this SQL Server.  I'm thinking I will have to update something in the registry, but not sure at all what that would be or where to find it.  

Thank you for your help.
