I'm using the excellent routine from Craig Boyd to send mails from VFP using SendViaCDOSYS.

But, I have a weird problem.
In some PC's [CDO] works perfectly, but in other Pc's with the "same example", using the same configuration gives me an error:
1429 "the transport failed to connect to the server".

Can somebody give me a clue that can be happening ?

I already turned-off the firewall, anti virus, etc.

T.I.A.
