smtp errors with IIS4

[dkn]

I have two web servers running NT4 with IIS4. One (a test server)I built from scratch installing everything myself, the other (a prebuilt corporate server)was pre-installed. I migrated a complete web site over from the test server to the corporate server and the only thing that didn't work
was cdonts and emailing via asp - I keep getting the Error 'ASP0115 - A trappable error occurred in an external object. The script cannot continue running'. This error never occured while I had the site on the test server

I have been trying to get some ideas about this error but it seems it covers a very wide range of problems. I have compared the configuration for SMTP on both servers and they are the same. Could this be incorrectly registered dll's?? Has anybody come accross this problem before as it is driving me NUTS! Please help!

Thanks in advance.

...I've noticed that before the trappable error occurs I get the error

"Microsoft VBScript runtime error '800a01ad'

ActiveX component can't create object

/email.asp, line 117 "

this is generated from the following asp code in my page email.asp

111 ' Create an instance of the NewMail object.
112 Set objCDOMail = Server.CreateObject("CDONTS.NewMail&quot
113
114 ' Set the properties of the object
115
116 'This syntax gets you the appearance of a real name!
117 objCDOMail.From = strFrom

Is there any EASY way to check the correct dll's are present and they have the correct permissions??
