Please help me output. I have tried netsh winsock reset catalog
The output of netsh int ip reset reset.log
is :
`Resetting Interface, OK!
Resetting , failed.
Access is denied.
Resetting , OK!
Restart the computer to complete this action.`
I have also tried netsh advfirewell
ipconfig /flushdns
ipconfig /registerdns
rout /f
without any luck. Please, Please help me out. It's really frustating without lan.
Edit: I am using the Intranet of College. Other friends of mine also can't ping 8.8.8.8
but can ping the proxy servers just like me. i somehow feel that DNS is not an issue. When I open the browser it asks for "Proxy Credentials" and tries to get connected(blue circle rotating) but it get stuck and shows "Performing TLS Handshake". This thing happens across all browsers that I have tried.
Best Answer
Well, there are a few potential problems here. I'll cover them one at a time.
Disable IPv6
First, it's possible your computer is attempting to communicate via ipv6 and failing. This is a surprisingly common problem when Windows thinks you have ipv6 support but your ISP does not, in fact, fully support it.
You can disable ipv6:
control ncpa.cpl
into the run dialog and clickOk
.Properties
from the drop down.Internet Protocol Version 6 (TCP/IPv6)
and uncheck the box next to it.You may have to restart for the settings to take effect.
If this turns out not to be the problem you can simply re-check the ipv6 feature and re-start to re-enable it.
Fix Your DNS Config
I notice you have an RFC1918 IP address for your DNS server. In addition, the DNS ip is not part of the subnet your computer is on. There are two primary circumstances where this would be correct. 1): Your computer is on a large company intranet that is subdivided into multiple subnets and has a DNS server on another part of the intranet with a router handling communication between parts. 2): Your ISP uses RFC1918 ip addresses internally (uncommon, but not unheard of). In most cases, however, this would be an invalid configuration.
It's also possible there is simply something wrong with the DNS server, either permanently or temporarily.
First thing to check is to see if you can use DNS:
nslookup annapuma.onsite-crt.com
.You should see:
nslookup annapuma.onsite-crt.com 8.8.8.8
instead. This will use a different, publicly available DNS to resolve the address but should give the result mentioned above.If #3 works but #2 does not then you need to change your DNS settings. 8.8.8.8 and 8.8.4.4 (Google's OpenDNS) are excellent choices for DNS if you don't need internal DNS resolution for a private network.
To change your DNS settings:
control ncpa.cpl
into the run dialogOk
.Properties
from the drop down.Internet Protocol Version 4 (TCP/IPv4)
Use the following DNS server addresses
radio button8.8.8.8
into the "Preferred DNS Server" Box8.8.4.4
into the "ALternate DNS Server" BoxOk
Ok
Disable Browser Proxy
Your web browser may be configured to use a proxy. A quick test for this would be to telnet to an http server.
telnet annapuma.onsite-crt.com 80
You should see:
GET /index.html
You should see:
If this works and you still can't open pages in your browser then the issue is likely browser related and proxy settings may well be the issue. Bitdefender provides a guide for removing proxy settings that covers the most common browsers.
Something Else
There are quite a few other possibilities but these are by far the most likely. I would need more info if these do not solve your problem. If you manage to collect any additional info feel free to add the additional info to your question and drop a comment so I'll be notified.
