Hi all,
I am unable to reach a particular website from my home computer. But its easily accessible from office computer. I have cleared the cache in the browser, tried to flush the dns cache using ipconfig /flushdns. Nothing helps. Ping / tracert says - "Request timed out". Any pointers? Thanks in advance.

Short expert summary and a focused diagnostic sequence relevant to ’s reports and the suggestions from and .

The fact that the bank site works from the office but not from the home connection, and that clearing browser cache and disabling the local firewall did not help, points to a network-level issue (home router, ISP, or the client network stack) rather than a simple browser cache problem. Ping timeouts are not decisive because many financial sites drop ICMP; failure to reach the site by IP or from the same LAN is the stronger signal that packets are being dropped or filtered before the application-layer handshake completes.

Recommended diagnostic sequence (in rough priority):

  • Verify reachability from another device on the same home LAN and from a separate network (cellular data or another ISP). If other networks can reach the bank, the problem is confined to the home network or ISP.
  • Bypass the home path: use a VPN or mobile tethering. Success via VPN points to ISP/router filtering or routing problems.
  • Inspect the home gateway/router: reboot it, check for URL/content filters or an outbound firewall, and review DNS settings (router may be acting as DNS forwarder). Update router firmware if available.
  • Confirm DNS and name resolution with nslookup (which DNS server responds, what A record is returned). A mismatch here would steer toward DNS filtering or hijacking.
  • Reset the PC network stack with netsh winsock reset and netsh int ip reset, then restart the machine — this addresses corrupted stack or proxy remnants.
  • Run an AV/anti-malware scan; registry or proxy-based blocks are uncommon but possible with compromise.
  • If the site still fails from the home network, gather a traceroute and share it with the ISP and the bank’s support team so they can check whether the ISP's routing or their perimeter is blocking/blacklisting the home IP.

Practical cautions: hosts-file mapping or forced IP-to-host entries (as suggested earlier) can break HTTPS (certificate/SNI/virtual-hosting) and create confusing security warnings; editing the registry is risky without a full backup. For advanced diagnosis, a packet capture will show whether TCP SYNs are answered or dropped, which localizes the failure to a hop or device.

i know a great practical joke to pull by overriding the DNS if i have logon to your computer. so when you go to your favorite site it will take you to the site you hate.
ha ..seriously though how long this been going on?

Member Avatar for jingda

Maybe your firewall or other settings are blocking you from accessing that website.

Member Avatar for GyanPP

I have been trying the website from 1week and since then i have this problem. I'm trying to access a bank's website for internet banking.

I have checked the firewall settings too. In fact, once I tried to access it after disabling the firewall, still it dint help!

you should uninstall all of your network adapters from device manager, then right-click any device, and choose 'scan for hardware changes' and the adapters should be detected and drivers auto-installed. you will have to re-enter your wifi network settings.

Member Avatar for jingda

Your registry might be blocking the website. Go to your registry and type the web address of the banking site. You might want to clear all your browser data including cookies and cache files.

No, i am not able to enter through the IP address also. (http://<IP>)
Ping also doesnt seem to respond -

: Can you please tell me how to add the website in the registry?

Member Avatar for skilly

i assume all other sites are working, then? check content tab of internet options, disable content advisor if it is enabled.
what does say when you cannot connect?
check C:/windows/system32/drivers/etc/hosts (open with notepad)
if you see your website listed on this file, delete it

Member Avatar for GyanPP

Yes, skilly. All other sites are working. Content-advisor is disabled by default.
Hots file does not have the website. It reads -

# Copyright (c) 1993-2009 Microsoft Corp.
#
# This is a sample HOSTS file used by Microsoft TCP/IP for Windows.
#
# This file contains the mappings of IP addresses to host names. Each
# entry should be kept on an individual line. The IP address should
# be placed in the first column followed by the corresponding host name.
# The IP address and the host name should be separated by at least one
# space.
#
# Additionally, comments (such as these) may be inserted on individual
# lines or following the machine name denoted by a '#' symbol.
#
# For example:
#
# # source server
# x.acme.com # x client host

# localhost name resolution is handled within DNS itself.
# 127.0.0.1 localhost
# ::1 localhost

Member Avatar for skilly

type IP address& http address as shown in example in next line of file and save. this is that joke about bypassing external dns

For example:
#
# # source server
# x.acme.com # x client host

# localhost name resolution is handled within DNS itself.
# 127.0.0.1 localhost
# ::1 localhost
# www.onlinesbm.com

but remove #sign, save, you may have to take ownership to save changes to the file(it's not normal)
