I doubt this is a DCOM issue, but something higher up. Have you given read and write rights to the QuickBooks application folder (normally C:\Program Files\QODBC Driver for QuickBooks\) to the Anonymous web user IUSR_machinename, ASPNET user and INTERACTIVE? This allows for creation and update of QODBC trace and message logs and allows access to the DCOM server executables.

You should be getting an error when you run qbcust.asp.

Well not really, you will need to co-ordinate this issue and address any security settings with GoDaddy staff directly. There may be other Active X , port settings and router settings that may be causing your problems. Most hosting companies are pretty tight on the security settings on all the servers in their server farms.

Ok, if you're prepared to test on a test server, then why not try a Windows XP Pro notebook as it's a little easier using the procedure outlined at: How can I see QuickBooks data in a Internet Explorer Browser using Windows XP? again. 

You will also need to make sure IIS is installed in Windows XP Pro as it's not installed by default.

Now you have seen how it works, it should be easier to work on your test Windows Server 2003 you have. On the server console (local session) make sure that IIS and the Anonymous web user IUSR_machinename works correctly with a test ASP page first.

As I said earier, for you not to get any error message means it's not even getting to the QODBC DCOM servers. You have to make sure that VB Demo can do a "Select * from Customer" using the QuickBooks Data System DSN without QuickBooks running. Then make sure the DCOM servers are turned on in the QODBC Setup and permissions are set and go back to playing with qbcust.asp.

Don't forget to look at the IWAN settings on the server also.

Microsoft OLE DB Provider for ODBC Drivers error '80004005'

[QODBC] QB Open Connection Failed. Create DCOM Instance Error = 8000401a, Unknown error.. Created qbXMLRP2 OK.

/qbcust.asp, line 30

VBDemo works just fine, even when QB is closed. Regular ASP files run without problem.  QODBC is set to Server Mode (DCOM).  Where are these IWAN settings I'm supposed to check?

Ok, use the our automatic tool found at: How do I automatically setup the QODBC DCOM Servers?  then reboot the server and check the DCOM Settings as per How do I manually setup the QODBC DCOM Servers on Windows XP Pro and Windows 2003 Server? .

Make sure everyting is checked in the Security tab for qbXMLRPeInteractive and qbXMLRP2eInteractive:

and finally the Interactive identity:

The difference between Windows XP and Windows Server 2003 is security. Try giving the Internet Guest Account (<IUSR_<machine_name>), ASP.NET Machine Account (ASPNET) and INTERACTIVE accounts all rights to the C:\Program Files\QODBC Driver for QuickBooks\ folder and the following file in your System32 directory, I9K4UQLW.ocx. It may be a hidden, system file.

If you must use your remote Desktop, use this line to connect to the Foreground console on your Windows 2003 server:

mstsc /v:servername /console
