any ideas on OCI8 config with WIN

Help!!! I am trying to connect to an Oracle via windows NT4, I added the following line to y php3.ini file, "extension=php3_oci80.dll" I then restarted the server, Now when I try a simple connect to the database via OCILogon() the browser just sits there waiting for a reply. No error messages are returned. I then I used the phpinfo() function for view the configuration information and when I get to the row describing OCI8, the descriptive/Additional Information column is blank. What am I missing? Was I supposed to add anything else to the php3.ini file? Is this a bug? Please help. here is a sample of my code putenv("ORACLE_HOME=D:\Oracle\Ora81\NETWORK\ADMIN\tnsnames.ora"); putenv("ORACLE_SID=DB"); putenv("ORACLE_BASE=D:\Oracle\Ora81"); $conn = OCILogon("scott", "tiger"); if ($conn){ OCILogOff($conn); echo "Connected to database <BR><BR>"; }else echo "Not Connected to database <BR><BR>"; thanks Kevin
