Also dont forget to grant the Relay option for your SMTP server to allow relay from 127.0.0.1 n SMTP Server Properties ->Access -> Relay

How can I find out the name of my SMTP server if I don't already know it?

I set my SMTP server to "localhost".

Now I get a new error message:

Which OS are you using? Win2K or Windows XP? If Windows XP, then you might not have CDONTS.dll that is required in messaging. Grab this dll from any Win2K PC and register it using regsvr32 CDONTS.dll.

1. Copy CDONTS.dll to System32 dir.

2. Start -> Run -> cmd

type: regsvr32 c:\winnt\System32\CDONTS.dll

The Network Admin just recommended I  use "Local System" versus logging in  (under the Windows Service I am running).

This seems to have cleared-up the error messages as far as e-mail goes....but now I get another message (which I will post seperately).

Thanks,

Tom
