cant disply any webpage

[totallylost]

Ok

I have a cable modem with 3 computers on it. 2 of the 3 can go online no problem. the 3rd one just isnt wanting to cooperate Ive reset router cable modem and restarted comp. uninstalled and reinstalled my ethernet card. and still the little bugger will not open to any webpage. thats about it...

[degsy]

Is it getting an IP Address?
Can you Ping?

[totallylost]

nope i cant even get into the router through the address it gives me

[degsy]

Have you tried a different cable?
Have you tried a different NIC?

[totallylost]

ive tried a different cable and its still the same and i dont know what a NIC is so i couldnt try that. I check the ethernet card and it says its working properly but can it still be bad

[z1p]

Can you run 'ipconfig /all" from the command prompt on the machine that has the probglem and one of the machines that is working? This will show the network configuration for the machine. They should be the same except for the IP address.

[totallylost]

Well they are way off there isnt much that is the same. how would i go about changing the attributes on the computer that is not online...

[z1p]

That depends what is off and what OS you're running.
Here are the items that really matter.

Dhcp Enabled. . . . . . . . . . . : Yes
Autoconfiguration Enabled . . . . : Yes
IP Address. . . . . . . . . . . . : x.x.x.x
Subnet Mask . . . . . . . . . . . : 255.255.255.0
Default Gateway . . . . . . . . . : x.x.x.y
DHCP Server . . . . . . . . . . . : x.x.x.y
DNS Servers . . . . . . . . . . . : z.z.z.z
a.a.a.a

So what items are different? Most of these are set through the IP Protocol Properties buried in network connections under the control properties.

Are you using DHCP and have auto config enabled on the 'good' PC?
If yes, then make sure 'Obtain IP addr automatically' and 'Obtain DNS server automatically' are set. If those are set the rest should follow.

If you aren't sure what I mean, or changing these setting don't clear things up, post back and I'll provide more detail. If you do need to post again please let me know which OS your running and what state these settings are in.

[totallylost]

okay everything is cool up to the default gateway which has nothing. the dhcp server there is nothing. there is no dhcp server. and there is nothing listed for the dns servers.

I am running windows 2000 professional. i have done this once before but its been awhile so if you could give me instructions on how to change those settings i would appreciate it. the only thing i remember is attrib. thing and that is kind of vague now too.

[renegade600]

what happens when you bypass the router and connect directly into the modem?

[totallylost]

absolutely nothing. I open up internet explorer and it gives me the page cannot be displayed, with a dns error or something. i restarted the computer also after i connected the cable modem directly.

Can you connect with a Different Browser?

OK. I'll try to provide a little more details (I have access to w2k box now), but hopefully not too much.

Here's a mapping of the output of ipconfig and where that item is set under w2k. This various between window versions.

HOSTNAME -> Right click 'My Computer', select Properties.
Select the 'Network Identification' tab, then Properties
'Computer Name' maps to HOSTNAME.
This must be unique for each machine.

PRIMARY DNS SUFFIX -> Same as above, then click the 'More...' button
This would usually be the same for machines on the same
subnet, but it doesn't have to be the same.

NODE TYPE -> I don't know what this is, I've only seen it set to 'HYBRID'

IP ROUTING ENABLED -> Set through the registry on W2K
This should be set to NO, unless you have a specific
reason to change it.

WINS PROXY ENABLED -> Again, set through the registry on W2K
I would also expect this to be disabled.

DNS SUFFIX SEARCH LIST -> Open the 'Control Panel' and select
'Network and Dial-up Connections', then
'Local Area Connection'. Then click 'Properties'.
Select 'Internet Protocol (TCP/IP)' and click 'Properties'.
Click 'Advanced' and select the 'DNS' tab.
Most of this tab will be left alone for a home network,
unless your ISP tells you otherwise.

CONNECTION-SPECIFIC DNS SUFFIX-> See 'DNS SUFFIX LIST'

DESCRIPTION -> Tells you what NIC card is used for the interface

PHYSICAL ADDRESS -> This is the MAC address for the interface. This
is almost always set in the hardare (NIC card) and must
be unique for all machine on the subnet. You should have
to worry about this one.

Now on to the what you're probably most interested in...

DHCP ENABLED -> Open the 'Control Panel' and select
'Network and Dial-up Connections', then
'Local Area Connection'. Then click 'Properties'.
Select 'Internet Protocol (TCP/IP)' and click 'Properties'.
Selecting 'Obtain IP Address automatically' enables DHCP
Otherwise, you need to specify IP, netmask and gateway

IP ADDRESS, SUBNET MASK, DEFAULT GATEWAY -> See 'DHCP ENABLED'.
If you don't use DHCP these need to be set. Either your
ISP will provide the values for this or if you are running a
private subnet behind a router you need to come up with
these values. SUBNET will most likely be 255.255.255.0
and GATEWAY would be the internal IP of your router. IP
would be a unique IP on the same subnet as the internal
interface of your router. (Using DHCP is simplest)

DNS SERVERS -> Again see 'DHCP ENABLED'. If DHCP is enabled, then you
can either select 'Obtain DNS server address automatically'
or enter the IP address(es) for the DNS server(s). If DHCP
is not enabled, you must provided the addresses of the
DNS server(s). If you need to enter the addresses your
ISP should provide them.

PRIMARY WINS SERVER,
SECONDARY WINS SERVER -> See 'DNS SUFFIX SEARCH LIST'.
Select 'WINS' instead of DNS. These most likely don't
show up for a home network, but if you need to set
them this is where you do it.

LEASE OBTAINED,
LEASE EXPIRES -> These show up if you are using DHCP.


I hope this helps. Just match up the settings on the good and bad
machines, except for IP, and hopefully it will start working. If not post back
and we'll take it from there. If you have to post back let us know what your DHCP settings are on the machine.

Well i checked all the settings and they match up fine with the other comps. my DHCP settigs are enabled so where do i go next.
