Excel 2007 :: Generate Single Sheet Workbook And Save To Sharepoint Site

Automating Excel from Access, I'm attempting to generate a single sheet workbook and save to a Sharepoint site. This process works fine on my machine (XL2007, XP), but on a coworkers computer (XL2003, XP), the code throws a 1004 error on the save as line. However, the really odd thing is that stepping through the code doesn't throw an error on the coworkers machine.

Here's the sub being ran; the line it errors out on is the first branch in the .saveas block.

Code:
Private Const csSharePointSaveAs = "\sharepoint-us.mycompany.comsitesfinance adminlah blahlah-blahCustomer Publication Tracking.xls"

Private Sub PublishXLtoMOSS()
Dim objXL As Excel.Application 'Object
Dim wb As Excel.workbook 'Object
Dim ws As Excel.Worksheet 'Object
Dim rs As DAO.Recordset
Dim i As Long

'Set objXL = CreateObject("Excel.Application")
