Using CDONTS on Windows 2003 Server?<\/p>\n

Issue<\/p>\n

When using CDONTS on windows 2003 you recieve the following error message<\/p>\n

Server object error ‘ASP 0177 : 800401f3’
\nServer.CreateObject Failed
\n.asp, line ‘x’
\n800401f3<\/p>\n

Resolution<\/p>\n

Microsoft Windows Server 2003 no longer supports Collaboration Data Objects (CDO) for NTS (CDONTS). Therefore, applications that use CDONTS will not function on Windows Server 2003.<\/p>\n

Windows Server 2003 provides improved alternatives to CDONTS. To make CDONTS functioning on a Windows Server 2003-based computer, use one of the following solutions:<\/p>\n

OPTION 1 (if you need CDONTS):<\/p>\n

1. Download CDONTS.ZIP<\/a> file from here<\/a> . Once you have downloaded it unzip the CDONTS.DLL and put it into %systemroot%system32 folder (C:Windowssystem32 by default).<\/p>\n

You can also find CDONTS.DLL from your Windows 2000 CD if you have one.<\/p>\n

2. Register CDONTS.DLL on your server using the following command:<\/p>\n

regsvr32 “%systemroot%system32cdonts.dll”<\/p>\n

3. Once registered CDONTS.DLL you will need to make sure that Microsoft SMTP service is installed and running.<\/p>\n

OPTION 2 (using CDOSYS):
\n=====================<\/p>\n

Instead of using CDONTS use CDOSYS<\/p>\n

Code example:<\/p>\n

=======<\/p>\n

Set m = CreateObject(“CDO.Message”) m.From = “user1@company.com” m.To = “user2@company.com” m.Subject = “test 1” m.TextBody = “hello there” m.send<\/p>\n

======<\/p>\n
