hi,
whenever i am trying open us based sites like microsoft.com/msn.com/mcafee.com/yahoo.com they are not opening but if i open indian sites like indiatimes.com,yahoo.co.in etc it opens immediately. can anybody tell me what will be the problem. i scanned by pc with avast Anti virus, super antispyware, also with tuneup utilities but did not find anything. is this problem with ISP or my pc.

sb21pro · 10-03-08, 03:24 PM

r u serious almost 75 % of the sites are hosted in us, so no probs with us based sites ok
now u could try a different dns like 208.67.222.222

Admin · 10-03-08, 03:29 PM

Try using open dns.

By the way this site is also hosted in USA ... Assuming that you are using the same connection ... its your DNS which is creating this issue not USA bandwidth.

essbebe · 10-03-08, 07:07 PM

@query4u
Please mention your modem/router model details.
Usually the MTU has to be changed to 1492 or lower for this problem.
If OS is Vista the program below will/may not be effective.
Try DR TCP!
Download DrTCP 0.21 - DR TCP - a internet speed connection optimizer. - Softpedia

Sounds like a DNS problem , try Open DNS as suggested above

===============
Open DNS Servers:
===============
Preferred DNS = 208.67.222.222
Alternate DNS = 208.67.220.220

1. Select Control Panel from the Start menu.
2. Click Network Connections from the Control Panel choices.
3. Choose your connection from the Network Connections window.
4. Click Properties button.
5. Select Internet Protocol (TCP/IP) and click Properties.
6. Click the radio button Use the following DNS server addresses and type in OpenDNS addresses in the Preferred DNS server and Alternate DNS server fields.

hi

thanx to all for giving me reply. my router is D-link GLB-502T.Also the MTU value is 1492. Also i changed dns server to suggested DNS. i am using windows XP OS. even though i made these changes then also these sites are not opening which i mention.please give me solution.

Admin · 10-03-08, 08:31 PM

flush dns> restart pc> reboot router> change dns in router not on pc> try again if the sites open..

If not please post a screenshot of trace route to indiabroadband.net , u-tokyo.ac.jp and unimelb.edu.au

sb21pro · 10-03-08, 08:44 PM

try these dns
4.2.2.1
4.2.2.2
4.2.2.3
4.2.2.4
4.2.2.5
4.2.2.6

also try ping website

Admin · 10-03-08, 08:52 PM

Or You can try these :

172.31.6.5
172.31.7.197

The above ones which sb21pro has provides starting from 4.. they are anycast and used by verizon which will rout you through the nearest network available and they are the best ones to use if in North America but not here in India.
You will get routed through Bangladesh> Hawaii> USA main land and then a few more hope to the destination address.... all in all not the best ones to use

Dont forget to let us know if its working... I am worried for you. Hope this issue gets sorted asap.

And I forgot to ask> which ISP are you using?

smoothvibes · 10-03-08, 09:11 PM

i agree with admin, this is also US based site so it should not be the problem and if your connection is restricting US servers then this site should not appear on your system na

sb21pro · 10-04-08, 12:28 AM

hey admin i know that too
as posted above 4.. are not my first choice
but then if there is a option, then why not try

essbebe · 10-04-08, 12:47 AM

Also the browser you use . IE7 or FireFox 3.0.3 or newest Google's Chrome or Opera
Trying a different browser can pinpoint the problem.

query4u · 10-04-08, 12:10 PM

hi,
thanx to all for helping me. my ISP is bsnl. i kept my LAN setting as both IP & DNS on automatically detect setting. i am attaching modem setting pages. can you pls explain me where i have to make these changes, that will be helpful to me. i am using IE6.0, firefox 2.0.0.14. main thing is microsoft's site is not at all opening in both the browsers.

essbebe · 10-04-08, 12:25 PM

1. IN IE6 Tools Internet options security secure sites
add microsoft website in Allow category https:// etc ) ( from memory details given)

2. In settings.GIF enable obtain IP address automatically.
3. in Settings 1 uncheck enforce MTU ( now 1492) and try.
If still unable to access certain sites, restore MTU option.
Para two : Start Network LAn properties TCP/IP
properties
IN DNS enter 208.67.220.220 and 208.67.222.222

esperanza · 10-05-08, 12:25 AM

One word of caution with OpenDNS... if you have high latency to US sites (like I see now, ping slashdot.org taking 1.5 seconds) and you use OpenDNS, DNS queries will timeout left and right making web browsing very hard. Another thing, if you access google.com, OpenDNS will feed you some US-based server (google.navigation.opendns.com) and this will have the same high latency. If you don't use OpenDNS, you'll get a local server (im-in-f104.google.com, in my case) with ping times of <=100ms...

Of course, this is not really a problem if everything's OK otherwise with your connection (i.e., latencies are not bad)...

hitesh.07 · 10-05-08, 01:33 PM

Try 1454 mtu

query4u · 10-05-08, 03:28 PM

hi,
i tried by changing MTU value, also unchecked MTU enforce. also entered suggested dns in my LAN settings. also i added microsoft's site in trusted site. then also my problem not solved. msn.com,microsoft.com macafee.com not opening at all. when i am trying to ping them it's gives me request time out. can anybody tell me what settings i ve to do with my router. please send me the screen shots of router settings(each page), also LAN settings(TCP/IP properties) that will be helpful me to understand. may i take my router to service center for testing. please help me.

essbebe · 10-05-08, 06:02 PM

1.DLINK GLB-502T ADSL2+ Router configuration for BSNL dataone | I am sumeet

Quote:

2.Another option is bit complicated, u can use http tunnel to access blocked site for this Bypass Firewalls - Preserve your online Anonymity, Privacy & Security - HTTP Tunnel Corp
Go to this site and download the http-tunnel software
3.Use a URL redirection service like tinyurl.com

3. above used to shorten long Ip addresses.
Open tinyurl web site. type say a blocked Ip address.
Note the tiny url ADDRESS.
Retype in address bar of IE. does the web site open now ? else what error message you get.?
click this. http://tinyurl.com/1c2
[Open in new window]
4. Disable firewall program, or check settings.
also check windows firewall.
5.

query4u · 10-09-08, 05:55 PM
