Unexpected Database Login form - Crystal Report based on DataSet

I'm getting an unwanted database login form appearing when I set the Data Source of a Crystal report to a .Net dataset

e.g. myReport.SetDat aSource(myDataS et

This only occurs on some PCs, works perfectly fine on all my PCs (Windows 2000, XP Pro), and work OK on my clients XP Home machines

Problem only occurs on my clients XP Pro machines, these are out of the box Dell machines with XP Preloaded

Can't understand why only these PCs appear to be affected
I've built a Setup project and used this to install application consistently on all PCs
I've even built a simple report that lists just lists "title" from the "titles" table in the "pubs" database. This throws up the Database Login form on these PCs

Here is my code, the message boxes confirm that the dataset is filled and that there is only the one table in the datase

sqlDataAdapter1 .Fill(dsPubs1," titles")
MessageBox.Show (dsPubs1.Tables .Count.ToString ())
MessageBox.Show (dsPubs1.titles .Rows.Count.ToS tring())
rptReportTest rpt = new rptReportTest()
rpt.SetDataSour ce(dsPubs1)
crv.ReportSourc e = rpt

I think this may be a security issue of some sort (but I'm open to other ideas)
Are datasets held in memory or paged to disk
If they are paged to disk could it be that Crystal does not have access to the location of the dataset

Please Help Thank

I'm developing an VB.NET Windows Forms application that uses CR for VS.NET (original version shipped with VS.NET 2002 - my VS.NET has the latest SP installed, no SPs for CR).

I have a crystal report using a Dataset which is populated at Runtime. It works fine on my development machine, but when I deploy it to a test machine I get a 'Database Login' box.

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
