Try this
[vba] Dim wb As Workbook
Dim TheFile As String
Dim MyPath As String
MyPath = \\Server-1\production_share\Production Bucket Folder\
On Error Resume Next
TheFile = Dir(MyPath & "*.csv")
If Err then
debug.print Err.Description
Exit sub
End if
On Error Goto 0
Do While TheFile <> ""
Set wb = Workbooks.Open(MyPath & TheFile)
*CODE HERE*
wb.Close SaveChanges:=True
TheFile = Dir
Loop
[/vba]
And look at your immediate window in VBE (Ctrl+G) what the error description was. Are you sure that the network drive can be accessed? Or that there is no kind of security policy on it for VBA app's?
