Two w2k via router. IE6 on both. Since recently one of the computers
produces
"The page cannot be displayed" on every second attempt to access Internet.
Certain pages like the one in Yahoo where you login into a mailbox, cannot
be accessed at all. The other computer connects immediately

What needs fixing?

Two w2k what? Pro workstations?
Do you have the same problem when you ping an address, that accepts ICMP
messages, on the Internet?
What are the DNS settings on the workstations?
If your router is a NAT router, proving the ipconfig /all of the two
workstations would be helpful.

Is 192.168.1.1 the router?
What is the make and model of the router?
Ex. Belkin 54G Wireless

Are you running any DNS at 192.168.1.1?
What is the IP address of the primary DNS server on the private network?
If it is 194.74.65.69, what is between this subnet 192.168.1.0 and
194.74.65.x?
This may be answered by showing the make and model of the router but if not,
does the router have a built-in firewall?
If there is a firewall, what ports are open? Please specify port type also.
Ex.
Port 80 TCP

This may be the options you have on the router TCP/UDP/(IP/BOTH)

If 192.168.1.1 is the router and DNS is not being provided by the router,
then the Desktop is having a problem because its Primary DNS is pointing at
the router.

A router is not a DNS server unless it provides DNS services.
Your router may be passing DNS information on from your ISP. Is bt.net your
ISP?
The DNS servers you have listed above are:
ns7.bt.net
ns8.bt.net

Thanks, Roland

1. 130.57.4.70 works OK
2. Yes, 192.168.1.1 the router's IP
3. The router is Vigour2600x - actually it is a router and ADSL. I have no
idea if it is NAT or not. The manual says nothing about it. It is said it
have firewall.

How do I find out what ports are open?
How do I find out whether I am running any DNS at 192.168.1.1?
How do I fing out the IP address of the primary DNS server on the private
network? Private network - you mean the two computers attached to the
router? If so, I did not set the IP address of the primary DNS server

4. My provider is BT Broadband
5. 194.98.0.1 this appeared after my Admin istalled somethind to enable
this Desktop to connect to the company's LAN over Internet.
It also resulted in a second line appear in the list of Network Adapters in
Devide Manager. It sdhows the same adapter SiS900 appended with "Lucent VPN
Miniport"

6. A router is not a DNS server unless it provides DNS services - how do I

Actually it is a Vigor2600x:
http://www.draytek.co.uk/products/vigor2600x.html
It has all the features of the Vigor2600 and more. This link tells you what
those are:
http://www.draytek.co.uk/products/vigor2600.html

This answers the NAT question:

a.. NAT Port redirection, forwarding and DMZ
a.. Multi-NAT facility - enables a one-to-one mapping of public to private
IP addresses, with individual DMZ and port-formwarding.

a.. DNS Proxy/Cache & DHCP Server (with ability to fix allocations)

This is not a DNS server. Your desktop is pointing it's Primary DNS server
to the router. If the router could pass the information then you should
point it there but if not, then you're going to have to point it to the
ISP's DNS server and make sure port 53 is open on the firewall.

Most SOHO routers have a web interface. Browse to http://192.168.1.1 and
see what happens. If you have a manual, it should tell you what the default
logon and password is which might be admin/admin.

This link is probably important to have:

Thnks, Roland.
The deeper into the forest, the fatter the freedom-fighters are.
I thought that, as the literature says, to network two w2k to share files
and a printer one needs no network knowlegde. Just plug them into the router
and here you go.
No I see how naive I was.

1. 130.57.4.70 works OK on all the computers
2. "NAT Port redirection, forwarding and DMZ" - does not make things any
clearer for I do not know what DMZ is. Is it necessary to study the whole MS
Network+ Certification Course to make two w2k work together :-) ?

3. > This is not a DNS server. Your desktop is pointing it's Primary DNS
server

point it there but if not, then you're going to have to point it to the
ISP's DNS server and make sure port 53 is open on the firewall.
Click to expand...

Oh, God!
a. How I learn if the router could pass the information ?
b. How do I point it to the ISP's DNS server and make sure port 53 is open
on the firewall ?


4. I can browse to http://192.168.1.1 and login to the router settings.
But I am very nervous about tempering with them because two other computers
on this router work fine, therefore the problem should be in the computer
settings, rather then with the router, and changing router might make
problems on the other computers, might it not?
However the existing TCP/IP and DHCP settings might be of interest:

LAN IP Network Configuration

1st Subnet Mask : 255.255.255.0

I hope not. I'm not A+ certified!
DMZ is the same as it was in Korea, Vietnam. DeMilitarized Zone. In IT,
DMZ is an area that has no protection and generally sits between two
firewalls or off to the side but never within the private network.
Companies who host their own Internet web servers may choose to put them in
the DMZ. It's not a good idea to let public traffic mix with private unless
a VPN is used and then it's not really public although it may travel across
a public network, like the Internet.

Simple. Use nslookup which uses port 53 from one of the workstations. Type
this in:

nslookup -q=ns bt.net

What you should get is:

Server: (the FQDN (fully qualified domain name) of your DNS server)
Address: (it's IP address)

Non-authoritative answer:
bt.net nameserver = ns1.bt.net
bt.net nameserver = ns2.bt.net
bt.net nameserver = ns0.bt.net

ns0.bt.net internet address = 194.72.6.51
ns2.bt.net internet address = 217.35.209.188

I got a non-authoritative answer because I do not have a bt.net zone in my
DNS.

You will have to do this on the workstation that is working but try on both.
The other should have an issue.

: 4. I can browse to http://192.168.1.1 and login to the router settings.
: But I am very nervous about tempering with them because two other
computers
: on this router work fine, therefore the problem should be in the computer
: settings, rather then with the router, and changing router might make
: problems on the other computers, might it not?

I would check the network settings of the router that is not working and
compare it with one that does. One of them, IMHO, is setting the primary
DNS setting manually. If the one that works is manual, set the one that
doesn't work the same. If the one that works is dynamic, then set the other
accordingly. I don't believe you have to reboot on W2K after modifying the
Primary DNS server.

: However the existing TCP/IP and DHCP settings might be of interest:
:
: LAN IP Network Configuration
: For NAT Usage
: 1st IP Address : 192.168.1.1
: 1st Subnet Mask : 255.255.255.0
: For IP Routing Usage : disabled
: 2nd IP Address :192.168.2.1
:
: 2nd Subnet Mask :255.255.255.0
:

: Server Enabled
: Start IP Address : 192.168.1.11
: IP Pool Counts : 50
: Gateway IP Address : 192.168.1.1
: DHCP Server IP Address for Relay Agent : blank
: DNS Server IP Address blank

If you set this line above to the bt.net primary DNS address, it may provide
it for the computers that are set to obtain DNS via DHCP or automatically.
One of these should do it:
ns0.bt.net internet address = 194.72.6.51
ns2.bt.net internet address = 217.35.209.188

You only need the address.

: Primary IP Address : blank
: Secondary IP Address: blank
:
: Dynamic DNS Setup is not enabled

If you enable this, it may obtain the DNS automatically from the ISP and
with the DHCP being provided to the workstations, if they are set to get
their DNS settings automatically, then they should get it from the router.

: RIP protocol control - disabled
: NAT setup:
: Private IP Address Range defined by RFC-1918:
:
: 10.0.0.0 --- 10.255.255.255 (10/8 prefix)
: 172.16.0.0 --- 172.31.255.255 (172.16/12 prefix)
: 192.168.0.0 --- 192.168.255.255 (192.168/16 prefix)
:
: DMZ Host Setup
: everything blank
: Port Redirection Table is empty except 0 for all public ports

If the others are working, I'm sure port 53 is allowed to pass. Nslookup
can confirm it. I'm betting that the ones that work have their DNS settings
set manually (static). I believe the one that is not working has everything
set to get it from the DHCP server but the router has DNS turned off so it
cannot provide it.

Thanks, Ronald.
1. It gets harder and then easier. It's hard trying to figure it out and
when you do, you say, "That was an easy fix."

Is it? You are not a Microsoft salesman, are you?
I have been suffering in this NG with the same question for two months now
and still oneone could offer a fix, even a not an easy one. You probably
noticed that thought I floated several questions, they are about the same
problem.

2. nslookup -q=ns bt.net returns:

Server: my.router
Address: 192.168.1.1
DNS request timed out
timeout was 2 seconds
DNS request timed out
timeout was 2 seconds
*** Request to my.router timed out

Please note that I have the same on the other computer which has no "The
page cannot be displayed " problem. Therefore it might not be relevant to my
problem. But in any case it should work as you predicted - what needs
fixing?

3. I got a non-authoritative answer because I do not have a bt.net zone in
my DNS.
How do I find out is I have a bt.net zone in my DNS?

4. I would check the network settings of the router that is not working and
compare it with one that does

I have just one router. All the "network" is two PCs and a router between
them. Well, there is a third PC there, but not to complicate things I
willnot discuss its problems for the moment.

4. Regarding setting DNS on the other computer - I looks like shooting in
the dark hoping to heat something. Why should I change these setting if they
had been working fine for the previous three months, and still work on
another computer?

As you said at the beginning "It's hard trying to figure it out and when you
do, you say, "That was an easy fix."
To be able to say that one needs to understand causes - so far simple logic
tells me that no pint to chane settings on one w2k if the work on another
w2k unless there is a clearly understood reason why.

Probably the result of nslookop mentioned in 2 give you a hint?

You get this because in my previous post I said the router it not providing
DNS information to the workstation that is having the problem. You either
need to enable it in the router or you need to point the workstation's
primary DNS somewhere else. Those are your only choices.

: Please note that I have the same on the other computer which has no "The

If it doesn't have a problem, then it doesn't need fixing.

That was informational. You SHOULD NOT HAVE one. You are not the
authoritative server for bt.net and if you try to be, they'll not be very
happy. That's called DNS hijacking but we'll save that for the security NG.

That was a typo. router should be computer.

You should only modify the workstation that has the issue. Do NOT modify
the workstation that is working. However, only you can provide the
information as to how the GOOD workstation is configured. You have to go
INTO the network settings to see. Ipconfig will not tell you how it got the
information for the DNS server. If it is static, meaning if it has a value
in there, you need to modify the BAD computer to be the same. If it is
dynamic, meaning it obtains the DNS information automatically, then you need
to modify the BAD computer to be the same.

answered above - don't change what works.

: Probably the result of nslookop mentioned in 2 give you a hint?

Yes. It told me something I already knew. The router is not providing DNS
information so you shouldn't point to it.

Thanks again,

1. You get this because in my previous post I said the router it not
providing DNS information to the workstation that is having the problem.

You mean my router provides DNS info to one PC but does not to the other?.
I wapped the slots in the router and this changes nothing. This means that
the problem is not in the router, but in the computer.

2. You either need to enable it in the router or you need to point the
workstation's primary DNS somewhere else.

Again I cannot compehend the logic of this. Two coomputers run the same OS
and are plugged symmetrically onto the router.
If one is working, the common sense tells me that the router and the
computer setting are OK, and instead of changing settings on one computers,
I should try to figure out what the faulty PC has set differently from the
right one.
I have the IP settings the same. But there are so many others IP and
network related settings wich just do not show up.
For example, I floated here a message about IP-routing. I have it enabled on
one PC and disabled on the other. But this shows up only on ipconfig /all
and nobody seems to know how to control this settings.


3. If it doesn't have a problem, then it doesn't need fixing.

I am confused. In the previos para I suggest I should change it, now you are
saying I should not.


4. You should only modify the workstation that has the issue. Do NOT modify
the workstation that is working.

This will result in two identcal w2k symmetrically connected to the router,
but configured differently - this makes me feel uncomfortable, unlese an
explanation is provided why.

5. However, only you can provide the information as to how the GOOD
workstation is configured.
All the settings in TCP/IP settings are identical.


6. > Yes. It told me something I already knew. The router is not providing
DNS information so you shouldn't point to it.

But how does the other workstation manage to cope with it?

Bad:
DNS servers: 192.168.1.1
194.98.0.1
Good:
DNS servers: 194.74.65.69
194.72.9.38 (I do not know
where these addresses came from. On the other PC I have the router address
here which seems logical)

Remember this? These are not the same. Just because they're both plugged
into a switch, built into the router, does not mean they are configured the
same.

The GOOD computer, a.k.a. the one that works, DOES NOT point to the router
for DNS. It points the BTs DNS Servers for Primary DNS and Secondary DNS.
If you check the network settings of this computer, it will show you how it
obtains the DNS information. Either it is static (someone entered in the
address manually) or it is dynamic (it obtains it automatically). It cannot
be both ways. You want to set the BAD computer the same way as this one is
set. Does that clear up the confusion now?

Exactly, Roland. At last we are coming to the point.
If you go back to this message of mine, it says that this is what ipconfig
/all returns
I am trying to understnd where this is being controlled from. I failed to
find these these addresses are expressly set.
Could you tell me where they are taken from? And why they are different in
each computer?

Are you telling me you do not know how to look at your network settings for
a given NIC?
On W2K:
Right-click on My Network Places on the desktop and select properties.
The default NIC name is Local Area Connection.
Double click it and choose properties.
Scroll down, if required to Internet Protocol (TCP/IP).
Double click it.
Tell me what you see for both computers and please identify which is which.

I see. If you mean the TCP/IP properties, I mentioned, that I have the same
settings on both computers and on both the DNS address fields are left
empty.

The other details of TCP/IP settings are
IP and DNS server addresses - obtain automatically
DHCP enabled
NETBIOS over TCP/IP enabled
lmhosts look up enabled (the adresses in lmhosts are taken from what
ipconfig returns in relevant computers)
DNS server address ? WINS address - empty
Apend parent suffix of the primary DNS suffix

What conclusions can you draw from this?

My conclusion is one of us is drinking! You cannot have dynamic settings
and obtain two different results on two computers on the same subnet, unless
you have more than one DHCP server, which you should not have. The only
other possibility I can think of is IPSec on one that is blocking TCP 53,
perhaps some other things but I've never run across anything like this with
them, i.e. personal firewall, proxy, ...

One workstation points to the router. One points to the bt.net DNS servers.
You do however have NET Port one-one Redirection. Perhaps port 53 is open
for one workstation and not the other. I'm reaching here but if the systems
really are setup as you say, then I'd look at the router.

Here they say the DNS passes automatically but you have dynamic DNS disabled
on your router. It is also hard to believe the GOOD computer gets bt.net's
DNS info configured automatically. It just doesn't make sense.

I'm not familiar with this router but from the docs, it should not be
passing DNS. If it is, and the GOOD computer does actually get it from
there, then something is blocking it, either something related to NAT on the
router or IPSec or personal firewall on the computer. A driver issue is
always suspect but I always confirm settings before replacing software.

My conclusion is one of us is drinking!

It must be the MS Windows who is drinking - from my 5 years experience with
MS I am ander a srong impression that it is always not sober.

One thing you should know:
My new network problems (before I had a problem of makeing the wetwork
printer work and periodocal "unexpected network error") started after my
Admin installed on one computer Lucent VPN client to enable me to access the
offcie network from home over the Internet. Lucent has been onstalled on the
second PC simetime ago, but it did not work, so he reinstalled it. Now I can
access my office network from both PCs, but cannot access each others.

I noticed that after VPN was installed, a second NIC shoes up in the list of
network adapters in tha Hardware Manager.
The second one names same as the first one with "Lucent VPN miniport"
appended to the name. (No physical adapter were added)
Both adapters are enabled. Is there a chanse that there is a confusion
between these two adapters?

BTW, the original problem - "The page cannot be displayed" sorted itself out
after I disabled and then re-enabled one of these network adapters. But I
still cannot open files on one PC from the other. I am getting "unexpected
network error" or "specified network name is nolonder available or "The
local device name is already in use"

If your VPN is connected, then the other route is not available during that
time. The OS will not know which way to send out the request. This is a
very simple, easy to understand explanation of that:

Nothing like a confused NIC to ruin your <%=timeFrame%>

see article listed above.

If the VPN connection is active, kill it and then try. Your VPN should only
be connected when you need it, not constant.

Ronald,
Thanks for that, yet it does bring any help for my case.
Of cource I am not trying to access remote corporate network and the local
one at the same time.
I know Lucent VPN client masks my local network, and I alway close it down.
Actually I even do not use it everyday. The fact that I read and send
messages here proves that VPN is not on, does not it?
