PC cannot see most of the network (and vice versa)

I am running a network with eleven PCs, most with XP, some with XP
professional.
As the network has now exceeded the XP Pro limit of ten, I have acquired a
server with Windows Small Business Server 2003 installed on it. There is a
separate router, but I use the Server as my DNS Server.
Following this change, two of my PCs (both XP) cannot see most of the PCs on
the network from within Windows Explorer. They can see them all through the
command prompt and they have had their IP addresses allocated by the server.

Over the same weekend, I loaded Norton Internet Security 2009 on some of the
PCS including the problem ones. I have Norton Internet Security 2008 on all
other machines.
Norton Network map can see all the other PCs.

Please can anyone offer any suggestions?

Thanks

Rob

Every version of the Norton Anti-Virus will break the browsing of the
network. Norton A/V has a module (Internet worm) which will turn off
the "NetBIOS name resolution." You should still be able to view the
other PCs via IP addresses. If you can see them by IP address, then
you need to look at creating an A/V access rule in order to allow your
LAN IP addresses thru it.

I woudl strongly suggest you remove this from all computers and get a decent
AV.

AVG, NOD32, Avira, you name it. All OK.
Avoid: Norton and McAfee.

In any case the whole point of a server is to avoid the problems of
peer-group working. With the server properly set-up as a central store there
should be no need for a 'cat's cradle' of interlinked shares. Which will not
work properly if there are more than ten computers anyway.
 
Thanks, that has helped me find asolution albeit a blunt one.

I have had to set accesses on a pc by pc basis.
 
I have used Norton for some years now without too much bother.
I shall leave it where it is for now (as I have paid for it), but I will
examine other options this time next year.
The server is not set up yet, and it may be some while before it is
completely ready, but thanks for your views.
