Hmm, puzzling! I don't have an exact answer, but perhaps there's something
here that might give you some clues.
Not sure about the "cannot discover any computers" or "do not get a full
connection to the internet in Network and Sharing", but none of (well, none
that I know of!) the Microsoft servers respond to "ping" requests, so the
lack of response to ping from www.microsoft.com
doesn't necessarily tell you
Try another destination for ping, such as yahoo.com or google.com.
I turned on both those settings on my small domain at home (single LAN) for
my Vista workstations and the "Network map" now displays and shows all of
the Vista computers (before turning on these settings, I got the message
that the network map was suppressed by default in the domain). The actual
"map" only shows "Vista -> Gateway -> Internet", but the other computers
(including the Windows Server 2003 R2 Domain Controller) are listed at the
bottom as "The following discovered device(s) can not be placed in the
Have you verified that the GPO containing the settings is in fact applied to
the Vista computer(s) using the gpresult command or the Group Policy Results
wizard? I assume you have a check mark in the "Allow operation while in
domain" check box for both settings.
Also, check that the Network Discovery exception is enabled in the Windows
Firewall configuration is Enabled.
What do you mean by "do not get a full connection to the internet in Network
and Sharing"? The only time I've seen that sort of thing (e.g. limited
network connectivity) is when the computer could not get an IP address from
DHCP, but then I would expect you wouldn't have domain connectivity either.
My router has a built in firewall and does NAT as well, so perhaps the issue
is not related to the "firewall".

It is perfectly useless to know the right answer to the wrong question.
