Vista - Network Printers

I have just done a fresh install of Vista Ultimate on my Dell Optiplex GX520.

All seems to be working fine except for adding network printers. I choose
"Add a printer", Then "Add a network,wirelss or Bluetooth printer". A dialog
comes up saying Searching for network printers, almost immediately another
dialog comes up saying windows explorer has caused a fault and is restarting.

Below is error details from event logs:
