Whoever from Microsoft told you that XP and Vista cannot share files and printers should be fired. They have no clue what they're talking about.

Microsoft addressed this interoperability issue with the LLTD client shortly after Vista was released. See my post above if you're still having issues getting Vista and XP to work together. I use Vista Business Ultimate at home, my wife's and kids computers are XP. We all see each others shared drives and printers just fine with the LLTD client installed on the XP machines.

Download and install Link Layer Topology Discovery (LLTD) onto the WinXP machines.

You are so right. This is the key. If you don't do this Vista will not share with XP!
