1. Don't know about the "cam". Have no real "Vista" experience", but have worked some with Windows XP file and Printer sharing.
If you don't have Vista drivers for the printer, I don't think you'll be able to print from the Vista machine, but you should be able to print shared Vista files from the Windows XP machine.
You may have to enable the "Computer Browser" service on one of the machines in order to see the resources of each computer on the other's "My Network Places".
If you have a functioning network, you would try to ping each computer from the other by IP address to ensure you have physical connectivity. You might have to disable or configure the LAN side firewalls to permit ping to go through (ICMP protocol, I believe). If successful, you would then ping each other by their computer name, e.g. "RedCloud" (NETBIOS) to ensure you have name resolution working.
You should then try to access the other computer's shared resources (using either the NETBIOS name or IP address where it says "ComputerName"):
Using Start-Run
1. Click Start, and then click Run.
2. In Open, type \\ComputerName\SharedPrinterName, and then press ENTER.
For example, to connect to the shared printer named COLOR on the computer named HOMESRV, you would type \\HOMESRV\COLOR. You can use upper or lowercase letters for the computer and printer share names.
If you don't remember the name of the share, you can do the following:
1. Click Start, and then click Run.
2. In Open, type \\ComputerName and then press ENTER.
You need to ensure "File and Printer Sharing for Microsoft Networks" is installed and enabled on the LAN connection. You also need to enable sharing for the files, directories, or printers you wish to share. You may have to disable or configure the firewalls to permit file and printer sharing.

Windows XP. For Windows XP file and print sharing see the following downloadable Microsoft documents. If you're impatient, it's OK to start with the "Troubleshooting" document first:
File and Printer Sharing with Microsoft Windows Troubleshooting File and Printer Sharing in Microsoft Windows XP 3.
Windows Vista. For Vista file and printer sharing try these links:
File and Printer Sharing in Windows Vista Troubleshoot file and printer sharing4.
Computer Browser Service. If you're looking in "My Network Places", people frequently complain about not seeing the "other" computers and their resources. This has to do with the "Computer Browser" service. At least one of the computers on the LAN (the one that's powered "on" most of the time), should have the "Computer Browser" service running. It will build and maintain a "master" list of the other computers in your workgroup, so when they go to look at "My Network Places" this list can be sent to them without having to build one from scratch for each request. Look at the following downloadable Microsoft documents (primarily for Windows XP):
