Internet Access denied

By tech ·
I have a PC with Windows XP Home S2. It works fine on the peer-to-peer network but will not access the internet via the internet explorer. I can ping external addresses by IP but not by name. All other PCs OK.
Any ideas please?

Internet access

by Info-Safety, LLC In reply to Internet Access denied

Colin,

Check the TCP/IP settings on your network adapter. If the other computers are set to automatically obtain IP address and DNS server address, make sure this one is as well, and make sure DHCP service is started.

I hope this helps.

you already tried turning the firewall off

by sgt_shultz In reply to Internet access

yes?
when this happens to me i rule out connectivity problems by tracert to my isp's dns servers (clue #1). if no problems there I try reaching an internet address by ip address. if that works i check for a spyware, viruii and or a hijacked hosts file (hint #2)
if you are really getting 'access denied' not 'page cannot be displayed' maybe try another user profile on that box, see if that gets you going. good luck

dump your M$ internet explorer and try using Firefox instead.

If nothing else, your denial of access error will appear about 15 times quicker.

TCP/IP Settings

by tech In reply to Internet access

Thanks, but tried this. The DHCP wouldn't work, so I set fixed addresses instead, that got the network going. Also installed a different NIC, same problem.

Ethernet

by al.damyanov In reply to TCP/IP Settings

Try to check for problems your ethernet driver. If everything is OK please give as more information about how to set up your TCP/IP Protocol. it has a several steps:
1. Put IP address for example 192.168.0.1 (or real IP address given from your ISP)
2. Put Subnet Mask for example 255.255.255.0 (or from your ISP)
3. Put Gateway - this is IP Address of gateway server of your ISP (the place in which you going out in the netork - internet)
4. Put DNS - this is Name server given from your ISP

If DNS IP is not correct you cannot receive anything in IE or Firefox. DNS job is to convert name to IP and IP to name.

You may check is DNS work with nslookup program which is started at console

c:\>nslookup
Default Server: gandalf.online.bg
Address: 217.75.128.9

>server ip.address.of.your.dns

for example:
> server 80.72.64.4
Default Server: ns.evro.net
Address: 80.72.64.4

> google.com
Server: ns.evro.net
Address: 80.72.64.4

Non-authoritative answer:
Name: google.com
Addresses: 64.233.187.99, 72.14.207.99, 64.233.167.99

If receive this:

> google.com
Server: ns.metizi-co.com
Address: 84.22.28.74

DNS request timed out.
timeout was 2 seconds.
DNS request timed out.
timeout was 2 seconds.
*** Request to ns.metizi-co.com timed-out

then your ISP doesn't geve you correct information.

You have more one variant to check the internet connection with using ping program in windows console

c:\> ping google.com
Pinging google.com [64.233.187.99] with 32 bytes of data:

Reply from 64.233.187.99: bytes=32 time=137ms TTL=242
Reply from 64.233.187.99: bytes=32 time=137ms TTL=242
Reply from 64.233.187.99: bytes=32 time=137ms TTL=242
Reply from 64.233.187.99: bytes=32 time=141ms TTL=241

Ping statistics for 64.233.187.99:
Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),
Approximate round trip times in milli-seconds:
Minimum = 137ms, Maximum = 141ms, Average = 138ms

If you receive a packets then everything is OK you already have a internet connection and they work. You mus search in other place problem.

If you receive Request time out, then you have a problem with connection.

This is manually setting up the TCP/IP futures.
Check is your ISP support DHCP for its clients.
