followed by the correct query results
2nd run (after killing db connection):

Can you add 'var_dump($dbconn);' after that odbc_pconnect() call..?
What does it output? (in the re-run)

Having reread all of this I see that nowhere have I mentioned I'm using
IIS (ISAPI) not Apache, if that makes a difference? I thought when I
put Windows in the OS box whoever read it would assume IIS.
In answer to your question "no", the behaviour is the same if
odbc.check_persistent is on or off.
The point is when it is off I would expect it to be my responsibility
to check the connection and would expect the error if I did not.
I would expect that when odbc.check_persistent was on odbc_pconnect was
supposed to check the connection for me if the connection it is about
to return from its pool is dead then it should discard it and create a
new one as when the pool is empty. Which is clearly not happening.

Well the nature of CGI doesn't really lend itself to supporting
persistant connections. It's run when requested and then exited after
that. So no data can really presist between pages that exists solely
in the CGI.
So this behavior only exists when odbc.check_persistent is turned on?

Yes still a problem under 4.3.0 I am using the ISAPI module. I don't
believe that persistent connections are supported at all under CGI. So
odbc_pconnect == odbc_connect which would give the illusion of working,
although the connection would not actually be persisting.
The first time you reload the page after killing the database
connection you get:
Warning: SQL error: No response from the backend;
Subsequent reloads give:
Warning: SQL error: Could not send Query(connection dead);

I'm unable to reproduce this on the UNIX end of things. Anyone with a
Windows boxen working that can test this?
