CDO Error

[JonWayn]

Im not sure that this is posted at the correct place but I hope I can get
some help here. I have a routine thats placed in a library mda project and
used on a few computers. It uses CDO to send a simple email. It works fine on
2 computers but just simply refuses to go on the other 2 its suppose to work
on. It fails with an error saying something to the effect "failed
*transport*server*". I have seen multiple posts online regarding this issue
and they all converge on the same solution which I have tried to no avail. I
use the standard configuration settings, SendUsing, Authenticate,
ServerTimeout, etc. Like I stated, it works on 2 PCs so I dont doubt that
those settings are correct. In fact, one of the 2 pcs on which it works,
doesnt even use the configuration settings. I added those settings to PC2
when I started troubleshooting PC3. So I have 2 methods of going about it
that work on separate computers, neither of which works on the others. Any
help would be appreciated.
