Try a static IP address & a static DNS.

Jamboree please post the results of an ipconfig /all for review before you make any changes.

Your DNS is being provided to you by your ISP. You are probably not going to be able to ping it but that does not mean it is not working. To test your DNS you need to ping something by its FQDN like...

PING YAHOO.COM

It you should resolve and IP for YAHOO and start pinging it. Try the command above and tell us what you get.

You could also try using a

IPCONFIG /FLUSHDNS
IPCONFIG /REGISTERDNS

This will flush your local DNS cache and reload. Then do...

PING YAHOO.COM
IPCONFIG /PRINTDNS

And you should see yahoo loaded in your local DNS.

I don't see anything wrong with that ipconfig output. I think he should be able to ping the DNS. Boot to safe mode & try it. There could be a conflict.

Some ISPs block ping packets on their DNS servers to prevent DDOS aatacks.

golly guys 194.168.4.100 pings just fine.

I would suggest the windows firewall [or other installed firewall] is blocking access

BTW Jamboree your mac address doesn't go across the router so no need to block it.

Hi All, thanks for your responses.

Pinging yahoo.com does not work, ie there is no response. Flushing the DNS and then re-registering had no affect either. Printing/displaying the DNS contents simply gave information about loopback.

In safe-mode I am able to ping the DNS server and browse the internet.

No windows firewall is not running on this pc, need to find out what is preventing access in full mode, any suggestions?

That means that there is a software conflict & the way to find it is boot to normal mode, run msconfig, go to the startup tab & disable whatever you think might be causing the conflict. A reboot is needed. You can go about it 2 ways. You can disable all right away or you can decide on your own.

In the meantime, if you want to post a Hijack This log, I'd be glad to look at it.
