Excel Interoperability Issues

Question

Hi, I am currently facing some issues over interoperability between .NET and Excel using VBA. I have an ASP.NET application, deployed at three different locations with following configurations: The excel features in the application have been developed using Excel ver 9.0 type library. Server1: OS : Windows 2000, .NET framework 1.1, Office 2000 Status: working fine. Server2: OS: Windows 2000, .NET framework 1.1, Office XP Professional Status: working fine. Server3: OS: Windows 2003, .NET framework 1.1, Office XP Professional Status: NOT WORKING. Any excel features, based on VBA, do not work. Those features that directly open excel docs using content-type header work ok. AND THIS IS THE SERVER THAT IS GONNA BE USED AS A PRODUCTION ENVIRONMENT VERY SOON... Please let me know, if there are any issues between excel 2002 and win2003. Regards, Maulik.
