Re: problem with PDO ODBC on Win2k3 server

I've actually solved it. By comparing the timestamps of the DLL files, 
and downloading various versions of the ZIP package, I found out that I 
was copying a thread-safe DLL into a non-thread-safe installation.

Is there a way to tell which version you have installed? I didn't 
install it originally on this server.

Hopefully this might one day help somebody making the same mistake if 
they find this message.
