Systemdb works in Access2000 but some problem in Access2002

ConnectStr = "DSN=MS Access Database;" _
& "DBQ=c:\temp\xyz.mde;" _
& "SYSTEMDB=c:\temp\abc.mdw;" _
& "UID=vvv;PWD=vvv;"

With ObjWord.ActiveDocument.MailMerge
.MainDocumentType = 0
.OpenDataSource _
Name:= c:\temp\xyz.mde, _
LinkToSource:=True, AddToRecentFiles:=False, _
Connection:= ConnectStr, _
SQLStatement:=ssql

I am using this piece of code in mail merge with secured
MSAccess2000 database and Word 2000. It works fine.

But when I use the same code for Office XP (MSAccess2002
and Word2002) and when I execute mail merge the "Data Link
Property " dialog window appears but by just pressing
cancel button the mail merge works fine.

I don't want to see the "Data Link Property" dialog i.e.,
there shouldn't be any user intervention while mail merge
takes place.

Appreciate your valuable time.

Thanks and Regards
