[Samba] Problem adding printer using MSRPC

[Guruswamy Namasivayam (gnamasiv)]

Hi,
 
When I try to add a printer using APW, the printer gets added
successfully. However, when I try to add a printer using the MS_RPC
addprinter command, the script fails with access denied. Please let me
know if I am doing anything wrong. 
 
Thanks,
Guru.
 
The addprinter vbscript
 
dim oMaster, oPrinter
 
  set oMaster  = CreateObject("PrintMaster.PrintMaster.1")
  set oPrinter = CreateObject("Printer.Printer.1")
 
  oPrinter.ServerName  = "\\abc.xyz.com"
  oPrinter.PrinterName = "Apple"
  oPrinter.DriverName  = "Apple LaserWriter 8500"
  oPrinter.PortName    = "Samba printer port"
  oPrinter.shareName  = "Apple"
  oPrinter.Location     = "odi-lab"
 
  oMaster.PrinterAdd(oPrinter)
