RUNTIME ERROR 2147024769 (8007007F)

I have an application developed in Visual Basic 6, SP6.  It is deployed and running on Windows 2000 Pro, XP, and Windows 2003 Server.
Using the latest and greatest Windows 2003 Server (w/SP1), the applicaiton no longer functions.  We get a "Run-time error -2147024769 (8007007f): Automation error.  The specified procedure could not be found".  We experienced this on a new Dell server, and also on a generic server we set up using Microsoft's 180 day trial version of w2k3.  This error does not occur on any other systems.
The exact line of code causing the error is the ADODB connection open (in this case to a MS Access file): "Provider=Microsoft.Jet.OLEDB.4.0;User ID=;Password='';Data Source=Database1.mdb;Mode=Share Deny None"
Microsoft's component checker reports no errors.  The MDAC version installed is 2.8SP1.  

Any ideas?  Thanks in advance for any help.....

Turns out that the msado15.dll  ( ver 2.82.1830.0)  supplied with server 2003 sp1  is not compatable with win 2000/XP. In fact, if we install this version on XP we  get the same automation runtime error we were getting with server 2003. The msado15.dll we are supplying in our install kit is ver 2.71.9030.0 and this causes the automation runtime error on server 2003.
