Can't view XP computers on Vista Notebook

I have been trying to hook up my new laptop(Vista) to my existing network
which has all XP computers. I was told it would be very simple, someone lied!

This is what I know about the configuration:

D-Link Wireless Router (although I am using it wired for this laptop)
3 PCs ( 1 is acting as server) all running XP
printer is connected to 1 of the other PCs
This laptop running Vista, I have follwed all of the file and print sharing
steps for workgroup and name, I can't turn on Printer sharing because there
is no printewr hooked to this machine.

I do get connectivity as I have internet, I just can't access the shared
files or printer on the other 3 machines. They are not visible at all.

Thanks in advance, Rick
