DNS Error when trying to connect to the Internet

[screwedup]

I have a 98 SE box that WAS working. IE 6.0 SP1. I tried to install wireless AP and then could not connect to the Net. DNS errors.

I uninstalled AP driver and got back to where I was before. Now I get the same DNS errors using wired connection.

I am connected to the net via a DSL line and an ADSL router.

I can ping addresses. I cannot connect using the full url.

I have disabled my software firewall.

Where are you getting DNS server info from? - DHCP from your ISP?

Try Start, Run, winipcfg What's listed for the DNS server for your ethernet connection?

Sorry for lack of info - Xmas noggin kickin in.

Speedstream 5861 router is configured for DHCP. I have an NT box talking to it now.

Winipcfg returns the Lan assigned Ip address correctly.
I can ping from the box to anywhere. I just cannot get to an Internet address with the alpha URL. I get a DNS error.

Also I cannot telnet from the PC. Do I have a port 80 problem?

Still need to answer the question from Smah. What's the DNS info. Since that appears to be your problem right now, don't worry about the other issues yet until your connection is straightened out. Methinks you still have configuration issues...

I encountered the same problem with my wireless router. Completely uninstall your software firewall. Reboot your computer. If it still doesn't work, connect your computer directly to the DSL modem to verify internet access. If you don't have access, unplug DSL modem's RJ45 connection for a few seconds, plug in, and powerfail the modem. After you verify internet access without the router, re-connect the wireless device. If you must, reset router to default settings. Use the RJ45 ports to verify IA.
My problem started after I installed the firewall application.
Good Luck...

Ok. DNS is provided automatically by my DSL/ISP provider.

DHCP is provided to the router from the ISP

DHCP is assigned to each PC on the LAN by the router. I now have an XP box up and running
-----------------

I de-installed the Norton firewall and rebooted. Same problem. I can ping external addresses but cannot access a web page.

Interestingly I cannot get to my router setup via the http: address. OS or IE configuration problem?

There is something wrong with either your router settings or the lan settings of your pc.

Start, Run, winipcfg

Your IP address should be in the range supplied by the router.
Your gateway should be the ip address of your router
Your DHCP server should be the address of your router
Your DNS servers should be that of your ISP (check their website)

Had the same difficulty with my LAN after a new Cisco router was installed. My server runs W2K and the workstations are all W2K Pro's.

The problem was an improper DNS server setting.

Get the preferred and alternate DNS server(s) from your ISP (They may provide an alternate).

Now go to your Network properties>local area connection>properties>Internet protocol(TCP/IP)>properties and change the "obtain DNS server address automatically" to "Use the following DNS server addresses".

Now fill in the DNS server info you obtained from your ISP. Do this on all your workstations and your server as well.

Don't change the "Obtain IP addresses automatically" option, though.

The DHCP service on your router should work just fine as it is.

Shut down your server and all your workstations. Restart the server first and test the browser. Be sure to have all your browsers configured for Internet access through the LAN. You should be on the Internet at this point.

Start up the workstations and check browser operation in a similar manner.

Your DNS problems should be resolved from here on in.

Hope this helps.

Go to a command prompt and type ipconfig /all. I had the same problem, until doing this I found out that my ISP was using 255.255.252.0 and the AP was using 255.255.255.0. Changed my laptop to fixed IP, using the same IP range and subnet to match the desktop which was wired to the ISP's cable/modem, all was well with the world. If you have a different subnet mask, you'll never see each other or the internet. Glen A. Johnson

if what ikudor does not work

you might want to extract your winsock files.
some times these files get corupt when installing a new router/firewall. even when you unistall firewall the damage is done.

the files to extract and replace is
winsock.dll
wsock.dll
and i think winsock.vxd
also remove dialup networking before doing the remove but to not reboot when it ask you to.
you can extract the files in SFC
you can look at MS knowledge base to find out the right files

this may help then again it may not..
i,m just offering some help.
good luck and hope this works out for ya..
as i know it gets pretty ruffwhen you cant surf the net.
