Tesco Broadband - DNS Problems?

My Tesco 512K connection is frustratingly slow at opening some web
pages - to the extent that it sometimes times out and won't open the
page at all. Results from on-line ADSL tests seem to indicate that
there's nothing wrong with the connection speed, and e-mail and
newsgroups are OK. Both my PCs do it (Win2K and WinME) and it isn't a
browser problem either (used IE Exploder and Netscrape).

So does this sound like it could be a DNS problem?

Maybe. Have you tried doing an nslookup to see what the dns server is doing?

No - what do I have to do?

For a start, learn to quote. Then people will get a clue of what you're
replying to.

F*cking Google groups...let's start again:

Me: Do I have a DNS problem

ABC: Maybe. Have you tried doing an nslookup to see what the dns server
is doing?

Me: No - what do I have to do?

From a command prompt the syntax is

nslookup domain name

examples

nslookup www.bbc.co.uk

nslookup www.google.com

The response should look something like this
Server: UnKnown
Address: 192.168.4.200

Non-authoritative answer:
Name: www.l.google.com
Addresses: 66.249.93.99, 66.249.93.104
Aliases: www.google.com

if you get

Server: UnKnown
Address: 192.168.4.200

DNS request timed out.
timeout was 2 seconds.
*** Request to UnKnown timed-out

for google or the BBC then you have a connection problem. If it takes a
while to return a ip address from your nslookup then that indicates a slow
dns server (and high latency).

From the symptoms you posted it does sound like a DNS lookup issue. You may
find that your ISP has alternative DNS server's you can use or alternatively
you could try a DNS server belonging to another ISP (I think this will
work).

Good luck
