Native connection to Oracle from PHP 4.0.6

I'm still having a difficult time connecting to an Oracle database from a win2k machine running php 4.0.6. The Oracle 8.05 client tools are installed on the machine, because there are asp scripts on the machine that are connecting to oracle. The oracle database is on another machine. The script is as follows: $db = "(DESCRIPTION=(ADDRESS=(PROTOCOL = TCP)(HOST = 206.195.71.234)(PORT = 1522))(CONNECT_DATA = (SID = radw)))"; $dbh = ora_logon("system@$db","manager <mailto:system@$db> "); And the error I'm getting is: Warning: Oracle: Connection Failed: ORA-12699: Native service internal error in c:\inetpub\wwwroot\radar\index.php on line 4 The oracle database is running 7.5, I think. I know the error from oracle says to run a trace to see what the error is, but since this isn't a machine I physically have access to w/o special request, I'd like to know if anyone else is using Oracle in thie environment, and if it's working, and HOW! Thanks!! Ricky
