Details:

Hello,

I would like to know if PostgreSQL (v8.2.3) Driver is compatible with
Win2003 Server 64 bits?

Because I can't connect at database remotely?

There are some special actions, options or instructions to do ?

I tried to open port 5432 from IP Filer and don't work.

Thank you.

Regards,
Bruno
