Cannot connect to printers in Vista



Hi,

I have a client that has a laptop with Vista Home Premium that owns two
stores and even though I have repeatedly setup her printers on her laptop for
both stores, when she leaves and comes back, she cannot print anymore.
Multiple times I have un-installed/installed the printer drivers, connected
directly to the network printer itself and through the print server on SBS
2003, but her laptop will not consistently print to the printers she wants
to. There are also a couple of shared printers that she needs to print to
but, again, it works once I get it setup, but then when she returns to the
store the next time she cannot print again. Any ideas would be greatly
appreciated.
