Solved i can ping to 127.0.0.1 but not to the localhost name

[leotina]

so here is my story

last week all of a sudden the wirelesslan gave me message limited access

now connecting my pc via lancable to a network gave me the message no connection to lan

ipconfig ---gave me just

Windows IP Configuration


ipconfig /all gave me

Primary Dns Suffix . . . . . . . :
Node Type . . . . . . . . . . . . : Peer-Peer
IP Routing Enabled. . . . . . . . : No
WINS Proxy Enabled. . . . . . . . : No



deinstallled the networkcard - deleted the driver load via stick new driver from intel plus restarts
reinstalled tcp on the networkadapter --- no success

found in some forums that ping to 127.0.0.1 must work -- which is in my case true
but trying to ping to the name localhost -- i get errormessage


my it-deparment told me new installation -- which in fact i could do
but my personel view of the things is different -- i want to know whats going on

basically i have time to solve the issue , cause i already typing this via my new pc

nevertheless i am eager to dig into the depth of windows

i kindly ask the community for usefull tipps --
my personell oppinion to problems

when there is a problem i have it
but after a certain period i am getting the problem for the problem
and that where its getting though for it

Hi Leo
don't worry it's just a name resolving problem/dns

what you have to do is open Notepad as admin (right click>> open as admin)
then click open a new file, after that browse to this location in your Pc:
C:\Windows\System32\drivers\etc\

and open the hosts file with notepad and add this line

127.0.0.1 localhost
and Save

dear oualid

thnks for response
tried your proposed action
i checked the file data as you mention above are there -- so i think we have to keep on diggin

 

[leotina]

dear all
one more remark: i verified 100% that the prob is not related to hardware
i swapped my hard disk to another laptop of same type still the problem
i took the harddisk from the other laptop put it into my pc all was the working fine

dear Leo

It sounds like your TCP stack is in some way corrupted.

This may clear the issue

Open a command prompt as Administrator and Run these commands one line at the time:

netsh winsock reset
netsh winsock reset catalog
netsh int ip reset reset.log
netsh int ipv4 reset reset.log
netsh int ipv6 reset reset.log
ipconfig /flushdns


Reboot if necessary

Try ping again

dear Oualid
following your advise find below the results
for better understanding it did it in the following way
as the pc is offline -- copied your commands to a usb stick
put the usb stick to my "bad pc" did all actions- put results back to stick and attached it below

If that's a full print out you don't have any network adapters is there any with yellow triangles in device manager?

 

[leotina]

dear samurai
thnks for your response
just quick info
in device manager i can see the networkcard without any triangle- i will send you screen shot
in 10 hours - so that you can see it yourself -maybe meanwhile you have another idea
so that i could also do this
nice day

 

[leotina]

dear samurai i attached screenshot as informed yesterday

 

[leotina]

dear all who helped me
actually it was kind of silly mistake from my side
is deleted below some time ago while trying to solve other problem
befor i did below i exported the registry -- which was the right move

now checking below link i found the solution
so after importing the registry i can ping now also local host

Start/Stop DNS Client service in Windows 7 from Services, Regedit or CMD


dear all thanks for your anticipation

 

[leotina]

so it was DNSCACHE in the registry i deleted erronuosly
