Hello,

I have a strange thing on allmost all computers on our network.
Most of the time there is no problem connecting to the internet, and
sometimes when you open IE browser, and type in a homepage it will not find
it.
We have a w2K server working as DC with DNS, DHCP, and WINS-server.
When this happens on the pc, you can open a DOS-window ping a WWW.jp.dk, and
it always answer. After this I can open my browser and now it works fine.
The Clients are w2k and XP with IE 5 and some with IE6

On the server the gateway is set to our router, and DNS is set to it self.
In the DNS I have put in our ISP's DNS adresses ind as forwarders.
The DHCP is set to give the client: GW = it is the router, DNS = it is the DC,
WINS = it is the DC and Node type = 0X8.

This is from the server.

On some of the Clients it is enough just to press enter one more time after
you typed in the www-adress.

I hope someone has any idea, because I have no ideas left.

Hi Jens,

On the clients, the DNS Search Suffix:
Søgeliste for DNS-suffiks. . . . . . . . . . : lederne.dk
is different than the domain it is a member of. Any reason why this is so?

As for the IE issues, what sort of line do you have? Is it ADSL? If so, that
can be an MTU issue due to the PPPoE overhead. Here's how to determine if
it's an MTU issue:

Hej,

It is an ADSL.
I have made the test from my pc, and I had to ping with an MTU on 1270 to
get a reply from my router, could that be right??

I have searched my registry, and after what I can se it is set to 1300.
I found this
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Interfaces\{DB5D2020-1F6E-4E2E-8F21-68813803301A}]
"MTU"=dword:00000514(1300)

If I do the same test from my server, there is no problems, I get reply from
the router with MTU on 1454.
In the registry on the server I can not see what MTU it is set to.

If I change it on my pc, do I get any other problems, or should I set it to
the same value on all my pc's??

Jens Jacobsen

ADSL is always the culprit when it comes to these issues. What is the router
set at? Maybe you can bump up the router to 1500, or 1492. That should work
with all the machines. 1500 is max packet size. I can't see why the MTU is
that low on your workstation. Backup that portion of the reg, then change it
to 1454, and try it, then try bumping it up to 1500 and see what happens.
