Vista - Vista computer not showing on network

Hi,
I have a wireless network as follows:
Desktop with XP, hardwired
Laptop with XP on network
New desktop with Vista on network
The new desktop computer with Vista shows the other computers on the network and I can share those files. However, the two XP computers do not show the Vista computer. They do show each other.
I did notice that the name of the network on the Vista is
"WORKGROUP". On the other two the name is "MSNHOME. Could this be the cause of the two not seeing the new Vista computer?
Thanks.
Pat

I'm not certain but it probably is the cause as I believe they all need to be in the same named group.

Have you made sure that the firewall on the machine isn't blocking access.

You also could check in the tutorial part of the site I'm sure there will be something there that will help you.

Hi....Thank you for your reply. I will look some more.
