DNS problem?

[Xerxes]

Hi,
I am having problems connecting to Internet on a Windows XP Pro PC
that is a part of a Windows 2003 SBS network.
First, it was giving me an IP conflict when there was no conflict. I
checked all other PCs and networked equipments like printers, and none
were using the same as IP as the PC in question. I changed the IP any
way and it seemed to work for a while. Now, I can access anything that
is local, I can ping other PCs, print to network printers, ... but I
cannot get out of the building. The server is set up as DNS server and
it can be pinged. I am not sure where to look for the problem. I think
something is wrong with the DNS resolution. Any help is greatly
appreciated.

From a command prompt;
ipconfig /all
on this pc and a working pc may reveal something.

I suggest a phone call to your system administrator.

I tired that, it didn't help.

I ran nslookup and got:
*** Can't find server name for address 10.10.11.20. No response from
server
*** default servers are not available
default server: Unknown
address: 10.10.11.20

I can ping 10.10.11.20 (the server) and any other PC on the network;
10.10.11.20 is listed as DNS server on the XP's TCP/IP setting; I have
no problem accessing files and shares on the server; I ran a virus
scan and found nothing; I ran ipconfig /flushdns, still no go.

I have another thought. Are you connecting to the Internet via an
ISP? If that is the case, and you haven't put every single site you
visit in your DNS, it may be causing this failure.

If you are using and ISP for connection (this is what I did for my
small LAN):

1. In your LAN connection setup, make sure that the DNS address on
the machine that provides DNS points to itself.

2. In DNS Administration, set up the forwarders to your ISP DNS
addresses. If you don't know them, you'll have to contact your ISP
and find out the IP addresses.

That worked for me. Maybe it will work for you?

Nothing seems to work. I even installed SP2 but to no avail.
When I ping the server (which is the DNS server), I get the result but
the server name is displayed as a bunch of garbage characters.
dnslookup keeps giving me "Unknown" as the server name. I have no
problem pinging if I specify the IP address.

If you are using an ISP for an internet connection, make sure your DNS
setup on the server uses Forwarders, and set those to match the DNS
servers of your ISP.

IOW:

1. Bring up the DNS Management Window

2. Right click on Whatever the Top entry is under "DNS" which should
be the name of your Server (Mine is simply SERVER since I lack
imagination).

3. Select Properties from the context menu.

4. Click on the Forwarders Tab of the dialog box.

5. Enter a DNS address of your ISP, then click Add. Do this for all
the DNS servers of your ISP.

6. Click OK and exit the DNS manager. You may or may not have to
reboot; I've seen this go both ways.

That's how I got my setup to work.

Maybe it would be better to move this discussion to a MS Server group
or Networking group; this is WAY beyond the topic of XP here.
