Browsing on Some Computers on My Network

[Michael]

Two of the PCs on my home network lose their browsing connections after I log
onto the Internet. Both are configured with Windows XP SP 3. Both detect on
my network management software (Network Magic) as being connected and working
perfectly; however, when I open any browser (IE, Firefox, Google Chrome), I
initially connect to a Web page but then cannot continue browsing, as further
links do not work. After the initial page, I lose the link. Consistently, I
find that I can reboot the system and open the browser again, but the loss of
network connectivity persists.

In the case of one of the PCs, from the moment it was set up, it did not
browse properly. In the case of the other, it has worked until recently -
the past two weeks, and now behaves in the same manner as the other PC.

In both cases, the DHCP appeared to be working correctly. Network Magic
indicates that both computers are connected to my network and are functioning
properly. I have also verified that my IP addresses for all the systems in
my network are configured correctly. What do I need to do to get my
connectivity to stay active once I reboot these PCs?

I've looked in the archives, but none of the similar issues are similar
enough to help me solve my problem. Anyone have suggestions that will lead me
to a solution?

Thank you,

When the problem occurs can you open a web site by IP address (to narrow if
this is a connectivity or DNS problem)?

Hi
NetMagic is a 3rd party application and it changes the Default inner working
of the Network, thus it is hard to direct a person how to go about
reconfiguring the system.
On a Normal Network (No NetMagic) this is the process.
Make sure that the Software Firewall on each computer allows free local
traffic. If you use 3rd party Firewall On, Vista/XP Native Firewall should
be Off, and the active Firewall has to adjusted to your Network IP numbers
on what is some time called the Trusted Zone (consult your 3rd Party
Firewall instructions.

This solved the problem on one of the PCs in my network, leaving only the one
I set up for my son.

I want to rate this one as helpful, since it solved one problem; however,
the problem on my other system is still open, so I don't want to close this
case down yet.

Thank you, Jack MVP

I have not tried this yet on the system that is still giving me issues. I
tried the firewall solution offered by Jack MVP, and while it solved my issue
with one PC, the problem lingers with the other.

A while back, I did receive a DNS error message regarding DNS tables during
one of my attempts to set it up on my network, but I have not seen this
message since. I do suspect that somehow DNS entries are at the heart of it,
but it is beyond my ken. The firewall issue resulted in this behavior:

I got on the Internet and used Google to search for Spider-Man (my son likes
Spider-Man, so it seemed a decent enough test search word). Google pulled up
a reasonable list of sites. I clicked the hyperlink to a page for images of
Spider-Man. Then, I clicked on an image of Spider-Man, and Firefox just
churned until eventually telling me that it couldn't find the page. I backed
up twice and then attempted to go to Youtube, and I got the same message
about not being able to find the page.

So, what solves this issue if it's not the native firewall on the PC?
