Macro Does Not Run On Different Computer In Same Network

I wrote a macro that runs perfect when started from my pc, but if started from a different ps which is logged into the same network it doesn't run, also the macro is stored on the server. I have a code in the private section of the workbook:

Private Sub Workbook_Open()
Call FINAL
End Sub

then the macro 'FINAL' is stored in the 'Modules' section and starts with:

Sub FINAL()
'this part opens the Edit/Links dialog from which the user has to choose the relevant model
Dim Which_financial_model_contains_the_data As String
ActiveWorkbook.ChangeLink Name:= _
"T:DEALSSSalsa (Project)Financial modelsProject Salsa Model - BASED ON SPONSOR CASE - b - 20061214.xls" _
, NewName:= _
"Which_financial_model_contains_the_data" _
, Type:=xlExcelLinks
