Oracle IAS version of Apache (1.3.12) & php_oci8.dll

All, I have the 1.3.12 version of Apache installed (via an Oracle install -- no source) on a Win 2000 system and I have downloaded the manual verion of PHP (not the Windows Installer). I configured PHP via the SAPI method and everything works great, including access to SQLServer and Access (ODBC), until I uncomment the php_oci8.dll line in PHP.INI. The Apache service (which has a different name because of Oracle, but still seems to be APACHE.EXE) fails to start. It hangs and the Service Control panel reports that it failed to start. 1) How can I figure out where the actual problem is occuring? 2) Can I test the PHP install independant of Apache to prove that it is an Apache issue and not a PHP issue? 3) What special issues are there with OCI8 and PHP? Thank you for your help, Kurt Lund
