Hello, go to TCP properties and specify another primary DNS server IP in you Nic properties.
-The DNS server's you are using to resolve the site do not have current zone information about that domain. Typically this occures when an ISP used to host the DNS zone, the SOA has changed and someone forgot to ask the old ISP to remove the DNS zone to remove the double SOA and likley invalid domain information.

can you tell me step by step how to do that? i'm very new to this sort of thing.

 

by: mikeleebrlaPosted on 2005-09-26 at 07:31:27ID: 14958979

ipconfig /flushdns will clear your LOCAL computer's DNS cache, but if the DNS server that your computer is pointed to has an old dns record, then the old one will "come right back" so to speak.  To resolve this you need to point your client to a DNS server that has the "new" DNS record... apparently your friends are already pointed to a DNS server with the new record.

go to the TCP/IP properties of your NIC (from control panel (network connections), rightclick your NIC, choose properties, choose TCP/IP, choose properties,,, then put in the IP address of another DNS server.  Apparently the one you are pointed to now has old info.

if i'm in the right area, it has two options:
- obtatin dns server address automatically
- use the following dns server addresses


obtain dns server address automatically is selected

how do i know which dns server to use? i'm on rogers cable if it makesany difference

 

by: mikeleebrlaPosted on 2005-09-26 at 09:28:35ID: 14960174

you can use ANY publically accessable DNS server... two of yahoo's are:

66.218.71.63
63.250.206.138

 

by: centaxPosted on 2005-09-26 at 10:03:31ID: 14960528

using those, i get a cannot be found for everything
i did a renew and release as well, just to make sure

 

by: mikeleebrlaPosted on 2005-09-26 at 10:13:00ID: 14960616

i just tested them and they work fine so your ISP must be blocking it so you can only use their DHCP assigned DNS server.  :(

 

by: centaxPosted on 2005-09-26 at 10:22:37ID: 14960689

so there's nothing i can do about it?

 

by: mikeleebrlaPosted on 2005-09-26 at 10:48:34ID: 14960938

from what you have explained, it sounds as though your ISP is blocking it,,,, there is nothing you can do about that other than switching ISPs.  If you wait a while your ISP's DNS server will get the correct DNS info.  Until then you can go directly to the new IP address.  Ask your friends what the new IP is and you can access it by http://123.123.123.123 where 123.123.123.123 is the new address.

centax it's unusual for ISP's to block access to public DNS server in my expierience...

-First let me say, if you tell me the name of the site I could most probably tell you what to send to rogers to have them resolve the issue for everyone...   Here what I would need....
1. Go to run and type CMD.. at the prompt type ipconfig /all (enter)  -paste the results here for "DNS Servers . . . . . . . . . . . :"
2. List the domain name you cant reach...

Here is what I would do with that info;
At the prompt type...
nslookup -q=soa domainname.com. ns1.kumatech.ca.
-Look at the results....
nslookup -q=soa domainname.com. YOUR.DNS.IP FROM ROGERS.
-Look at the results.... do they differ.... they must!

Other good detail lookups ar
nslookup -q=a www.domainname.com. YOUR.DNS.IP FROM ROGERS.
-Look at the results....

nslookup -q=a www.domainname.com. ns1.kumatech.ca.
-Look at the results....


What's the point?
Nslookup can query for specific record types against specific servers... So DNS double start of authority and the typical invalid dns host records that result from this can be checked using your own pc running a version of windows NT...

i cannot figure out how to split the points? i would like to give half to mikeleebrla and the other half to Housenet

 

by: HousenetPosted on 2005-09-26 at 16:21:12ID: 14963341

I'm not sure about the points split, but you should send an email to "unreachable web site" contact and inform them of the problem...Anyone using your ISP DNS server's cannot visit the site and they are not aware of it.
