CDONTS

As you should know, on Windows 2003 Server, CDONTS was deprecated and CDOSYS is the new one Microsoft email sender component (read more on
Microsoft Website)

However, some ASP scripts will require CDONTS and customers can need CDONTS install.

So, to install CDONTS

[list=1]
# First, install MailEnable or other SMTP server. Make sure it is running.
# Download and unzip cdonts.dll to C:\Windows\System32 folder
# Register the CDONTS.DLL component on your server by clicking start >> run >> type :
regsvr32 c:\winnt\system32\cdonts.dll >> ENTER
[/list=1]

Now CDONTS should being work perfectly.
