I would assume that the ethernet connection on your server plugs into some sort of firewall/router, cable modem, or similar device?

DNS problems

by TobiF In reply to Can ping

It seems the DNS server you're using isn't stable enough.
I didn't understand what ping was successful, but if fails, but works, then the ip address of the second address may have been cached somewhere near your computer.

What ip and dns settings do you have in your computer? (issue ipconfig /all in the command window)

ipconfig /all

Do you have a DNS server running on your server?

by TobiF In reply to ipconfig /all

I note that your IP address (on the Ethernet interface) is the same as the DNS address.

This means that whenever your computer needs to resolve an internet address (like into an ip address (like it will contact... itself.

So, there should be a DNS server running on your server. And this DNS server needs to be correctly configured.

Do you need your server to handle dns requests? (This could be the case if you use logical addresses within your local network, or if you want it to maintain the dns records of some internet domain)

If YES, then go find your DNS server program and its settings, there are some problems there.

If NO, then contact your internet provider and ask them for the ip addresses to their DNS servers. You should get at least two different addresses from them. As an alternative, you could rely on, a public dns service, for instance - Google (In that case, enter the following dns addresses: and

Is this ipconfig from your DNS server?

by seanferd In reply to ipconfig /all

If not, the DNS server address is wrong, as it is the same as the IP address.

DHCP is off, so you need to manually configure everything, don't forget.

You have no default gateway in your PPP adapter.

What is the Ethernet default gateway Default Gateway : Is this a router? If so, what is the PPP adapter for?

As to the VPN - DNS for the VPN is determined by the other end of the VPN tunnel.

This seems to be the domain controller itself. I believe that the dns resolver service on this machin is either absent or misconfigured (which might include pointing to an ISP dns with bad performance).

The PPP adapter was for dial-in. And nowadays we're so used to ethernet that we sometimes forget that PPP, being point-to-point, don't use netmask and gateway, since there's only one way to go...

To Clarify

by robo_dev In reply to Can ping

If you launch the web browser on the server, you cannot get to google?

Is the IP configuration for the server set to point to the router as the primary DNS server?

Can you ping the DNS server of your ISP?

Was this working normally at some point or is this a new install?
