Mark is right on this one. I went through the same thing and even had to install the ORAOLEDB.ORACLE driver with the 11g client from OTN, then carefully move the installation from the default 32bit to 64bit Program files directory to get Sql Server to see it to use for a bridge to an Oracle database. It's a known issue, as the driver isn't registered in the default directories that were commonly used before Server 2008..

To: "oracle-l@xxxxxxxxxxxxx" <oracle-l@xxxxxxxxxxxxx> Date: Friday, October 1, 2010, 10:49 AM I am nor sure but I am guessing that IIS wants the Oracle OLE drivers and on the last 9i cleint installation I did OLE is not installed as part of the default runtime. You have to go back and do a custom install and check the Windows components to get the Oracle OLE driver. With the 11g client I installed to use with SQL Server 2008 R2 I also had to do a non-default install to get the OLE pieces.

List, A colleague is configuring MS IIS on a Win2008 server (64 bit). Installed Oracle 10.2.0.4 client and confirmed that the client can connect to the database. IIS keeps giving the message "provider not found - may not be properly installed" We have done this before on Win2003 server (32 bit) and the Oracle 9i client. Any suggestions appreciated, Dennis Williams
