Can't see other PC's

[Fokke Nauta]

Hi all,

We have a small LAN with a few XP Pro PC's. They all can see each other and
sharing files is a piece of cake. Now we have bought a new laptop with
Windows 7 Home Premium. We also connected an AP to the LAN. Setting up an
internet connection from the W7 laptop was easy. But somehow the laptop
can't see the other PC's and vice versa. Pinging works fine. I managed on
the laptop to give the network group the proper name. I also managed to
install LLTD on one of the XP machines. Now this machine shows up in the
laptops network overview but I can't do anything with that. In My
computer/network the LAN does not show up and neither do the other PC's. The
laptop is invisable from the other PC's as well.
I never expected this new Microsoft product would be so crap. How can I
arrange that the laptop can see the other PC's and vice versa?

All network setting seem right. I removed the laptop from the home group as
this only works with other W7 machines.

Thanks in advance for your help.

With kind regards,
