There is a Windows Server SP2 machine in my office and it is not a domain server. No internet connection is possible in it from today.
First of all, I checked windows server 2008 cannot connect to internet and https://stackoverflow.com/questions/26821620/having-internet-connectivity-issues-in-windows-server-2008-r2 . These are not my issue
This system used to loose internet connection previously and a restarting was enough to solve it. But today restarting, troubleshooting or whatever I tried didn't solved this issue.
In this image it is written 'Tap Windows Adapter V9'. What is that ?
This is 'Network and Sharing Centre'
As you can see there is a 'Local Area Connection 4'. When internet connection was available there was one more 'Local Area Connection'.
Also I did 'ping' with 188.8.131.52 and with my router.Both was 100 % loss.
I only know this much to describe, because am not much familiar with Server editions. If you found this question as a stupid one don't ignore. Help me first and then do down-vote or delete... Help please.... If you want to know any more ask me. I will reply what ever I know.
