I am facing a strange problem with my VPS.

I can use the remote desktop to connect to my VPS just fine. This means my VPS does have a working internet connection. However once I am in, I can't open any website on the browser or use anything internet related.

I checked the proxy settings and everything's fine. (I am not using any proxy).

Any Idea?

Is it a new VPS?
What OS is it running?
You might need to make changes to the Group Policy or the server may not have been set up properly.

Its not new. I am using it for 4 months now I think.
OS is Windows server 2008.

Thanks for these links. I will check them out.
 
Seems like there' a problem with your DNS config.
I can take a look if you want (for free of course). Shoot me your skype.

Could be that DNS servers are not working - check in control panel, networking, nic properties, tcp v4 - try adding googles DNS (8.8.8.8) as a test.

Try a different browser if you haven't already.

Try from command prompt to ping an ip - ping 8.8.8.8 then try to ping a fqdn - ping google.com

Then report back.

The VPS was already set to use Google DNS. I tried switching to default DNS too but no changes.

I tried pinging ip (8.8.8.8).
got 4 replies each of 32 bytes. time 9ms. ttl=49

then i tried to (ping a fqdn - ping google.com).
ping request could not find host google.com. Please check the name and try again.
 
Check here -
C:\windows\system32\drivers\etc\hosts

Make sure no entries in there that could be modifying DNS queries (it's like a local DNS zone file).

Disable firewall if you have one - third party or windows firewall.

Maybe speak to your provider to see if they have hardware firewall that could be blocking DNS requests.

Scan for viruses - many viruses mess with the tcp stack and specifically DNS to reroute web queries so it could be that.
 
maybe ask your vps provider to help ?
Most often they solve these problems with just 1 support ticket

Looks like I will have to contact the service provider. I tried all of the above.

Also when I used a VPN (hotspot shield), the internet started working again on the VPS. When I switch it off, the internet stops working again.

Thanks for your help :)

Hmm, I'm guessing something is being blocked then, at the provider level and the vpn is circumnavigating that block.

Yea I think contacting provider is the best bet here.

Strange I had a similar problem with a brand new VPS but if it has been running fine then you probably need to contact your host/support.

Are you using the VPS for tools or hosting?

Check that you have Disabled Internet Explorer Enhanced Security Configuration

Then try to browse with IE. If you can't browse with IE use Remote Desktop Connection and transfer a copy of Firefox/Chrome/Opera

I have chrome and IE on the VPS and none of them work. I am using the VPS for running tools (GSA SER, Captcha breaker).

I will contact the provider on Monday now as they don't offer support on sat, sun.
 
Try these commands on a CMD as an Admin:

ipconfig /flushdns
ipconfig /registerdns
ipconfig /release
ipconfig /renew

That usually works for me

because ping of google.com is not working from command prompt either its unlikely to be browser specific. But rather it seems to be issue with DNS itself, or a firewall issue.

Just this part might work:

ipconfig /flushdns
ipconfig /registerdns

The last two wont work because I am guessing that IP is assigned statically so they have no effect. And if its not assigned statically then ipconfig /release will break your connection completely.
