B. NO BROWSING
-when you have a valid IP address but cannot open web pages
-test for browsing after each step
Step 1: Scan for viruses and spyware
-hopefully you are running antivirus and spyware protection programs.
-be sure to run a full system scan, one program at a time, and do not perform any other operations while these are running
-if you feel comfortable, you can also try the scan in safe mode for a more thorough scan
-if there are untreatable files, contact the vendor of the software for technical assistance

Step 2: Turn off firewalls and antivirus
-turn off XP firewall by clicking start, control panel (if it says "switch to classic view" then click there), open "Windows Firewall", turn off
-look to your system tray (the icons by the clock in the bottom right), hover over each icon, if it is a firewall or antivirus then right-click it and choose exit, shut down or disable
-IMPORTANT: in the program permissions of your firewall, make sure that "Generic Host Process for WIN32" is not blocked.
Step 3: Ping command
-click start, click run, type "cmd" without quotes
-in the command window, type with out quotes "ping www.testmy.net"
-if the ping goes through, there will be a "ping statistics" line. look for packet loss, and high round trip times
-if the ping is ok (no loss), proceed to Step 4: Restoring Browser Defaults
-if the ping says "unable to resolve host" or has 100% losses, try to ping by IP address
-type without quotes "ping 67.18.179.85", and check for packet losses
-if the ping by IP address is ok (no loss), try to browse by IP address: in the address bar of your browser, type 67.18.179.85...does testmy.net come up? If so, it is a DNS issue. Proceed to Step 5: DNS Settings
-if ping by URL and ping by IP address both fail, proceed to Step 6: Restoring TCP/IP
