Solved: Ping could not find host, DNS and key port problems
Hi, recently I had some malware on my Windows XP Professional (version 2002), so I followed a guide at Bleeping Computer (http://www.bleepingcomputer.com/viru...-security-2011) to get rid of it. Problem is, for some reason, after I finished, I could no longer access the internet!

When I try, FIrefox gives me their "could not connect" message:
"Server not found. Firefox can't find the server at [site]." Check the address for typing errors such as ww.example.com instead of www.example.com..."

When I try to log into MSN, the troubleshoot says I have a problem with my DNS and Key Ports.

I'm not good with computers so I Google'd and found some ping-ing instructions. When I tried to ping [site], I get:
"Ping request could not find host [site]. Please check the name and try again."
This happens regardless of the site I use.

Lastly, I tried "ping 127.0.0.1" from a troubleshooting site. It gives me:
"Pinging 127.0.0.1 with 32 bytes of data:

Reply from 127.0.0.1: bytes=32 time<1ms TTL=128
Reply from 127.0.0.1: bytes=32 time<1ms TTL=128
Reply from 127.0.0.1: bytes=32 time<1ms TTL=128
Reply from 127.0.0.1: bytes=32 time<1ms TTL=128

Ping statistics for 127.0.0.1:
Packets: Sent = 4, Received = 4, Lost = 0 (0% loss).
Approximate round trip times in milli-seconds:
Minimum = 0ms, Maximum = 0ms, Average = 0ms"

Any help would be much appreciated, thank you!

Do IPCONFIG /ALL in command prompt and post the information here.

Also if you do PING 98.137.149.56 do you get a reply?

The ethernet looks good and you have internet access. If you disable the wireless does the browser work?

I disabled it from Control Panel --> Network and Internet Connections --> Network Connections --> right-clicked Wireless Network Connection and disabled it.

It didn't work. D:

Also, apparently I have a "Connection Manager" called "MSN" that's "unavailable - device missing, F..."

Well definitley some type of DNS issue... one concern is that on the wireless connection your DHCP server and DNS server is the same as your computer's IP address...

While you do the instructions above, do you have a modem with a router connected or a modem with a router built in?
