Hi, Kirk

First, when you instantiate the report object, you need to set the servername. Here's some code, since you posted this under VB.NET (I pulled this from an old post, i haven't tested it, but it should either work or be close)

Dim logOnInfo As New CrystalDecisions.Shared.TableLogOnInfo()
Dim i As Integer
For i = 0 To report.Database.Tables.Count - 1                  <== Error on report
   ' Set the connection information for current table.
   logOnInfo.ConnectionInfo.ServerName = "server"
   logOnInfo.ConnectionInfo.DatabaseName = "DbName"
   logOnInfo.ConnectionInfo.UserID = "UserID"
   logOnInfo.ConnectionInfo.Password = "PW"
   report.Database.Tables.Item(i).ApplyLogOnInfo(logOnInfo)   <==Error on report
next

Second, you might want to consider designing your reports against either typed datsets or schema definitions.
