XP Pro cannot browse domain machines

Today I was browsing the network folders/mapped drives.
Suddenly I couldn't access them. Logged off and changed
the account as another administrator, had no problem
with the next account for a while. First the local sources
(domain computers/ shared network folder, etc) gone
then the internet access.

* I can login as domain user. There is no domain computer under the domain.

* I can ping IP addresses local & internet without a problem.

* I can ping local machines with their names but it takes a very long
time (~20 seconds.) and the replies are less than 3 ms. (in report)

* I cannot ping the internet (google.com)

* In the safe mode, everything is ok, I can see all the domain computers.

* DC server is Win2003 SBS. I have 19 used of 30 CAL.
Clients are XP Pro SP2.

* I have no problem with the domain account, I tested on another machine.
And other accounts don't work as I said. I tested with another ethernet card,
same problem.

* Looks like name resolving problem but I have no idea.

Now, what do you think and advice?

Thanks.

give us the output of 'IPConfig /all > C:\ipconfig.txt' from both the SBS
and one affected workstation.

If you feel you have to munge them do so in a consistent manner (but really,
there should be no reason to munge them other than possibly hiding your
public FQDN if you were silly enough to use it as your AD DNS name, maybe
remove the MAC addresses we don't need them anyway)

Two things:

1. DNS - make sure all clients and the server point *only* at the SBS
server's LAN IP for DNS. No public/external IPs listed for DNS anywhere but
in the forwarders on the DNS server itself within SBS. Make sure all your
servers/computers show up in the SBS server's DNS console (forward lookup
zone for my.domain.local)

2. Browsing = NetBIOS. Make sure NetBIOS over TCP/IP is enabled for all
devices (it will be, if you used SBS as your DHCP server). Then, make sure
all clients & the server point to the SBS server's LAN IP for WINS, as well.
Take a look at WINS on the server & make sure everyone shows up as
registering therein.
