ISAPI dll deployment problem

I have converted an ISAPI dll using BDE to IBO. On my dev machine using PWS
, but connecting to my server for IB6 --> everything OK.

When copy & run on IIS4 on my server (IB6 on same server),browser just hangs
, never returns with a response (blank window with progress bar), after
which the web pub service is messed up.

TO TEST I have build a very simple Isapi dll using IBO & also IBX, running
on server IIS4 --->IBX version works<--- , IBO produces identical behaviour.

What have I NOT got on my server to enable IBO db access ? Connection
string "servername : path" , cpTCP_IP, makes no difference with "localhost :
path" cpLocal.

I have NOT install IBO components into Delphi or deployed anything else on
my server,.
