secure website problem

well could be a multitude of different "things" [ configurations ] blocking traffic. there is also the matter of your DSL service. Verizon DSL service time to live DHCP ip address assignment is about 4 hours. though normally you'll get the same IP address for months at a time, if the computer doesn't respond to a DHCPACK message [acknowledging the DHCP server] then you might not get an IP address.

On the computer in question, open a command prompt by clicking start, then Run. In the run box type cmd, then click ok. a DOS type window will open. At the prompt c:\documents and settings\ type in ipconfig /all and press enter. copy down information such as IP address subnet mask DHCP server ip address DNS server address. then post back. if the address starts with 169.xx.xxx.xxx then there is not connectivity to your dsl service. you should have an IP address starting with a 4.xxx.xxx.xxx [verizon dsl service public block addressing usually is a class A address block].

also let us know that in the 24 hours that the service worked if service pack 2 was installed [little world globe in the tray on the lower right corner of the screen that you click and install updates]. Also provide us with how your network connection settings are setup as well as your Internet Explorer browser.

It does sound to me like you are infected with some malware.
I recommend checking your task manager and msconfig for programs you do not recognise. Any suspicious entries, check them by searching on google. Remove anything you don't need.
Hope this helps.

check for slammer and other viruii. also malware.
check in windows network connections, make sure nic that talks to verison dsl router has firewall turned on.

Download Adaware from download.com, run it and let it remove any spyware it finds. Make a note of any not removed, you may have to boot to safe mode and remove manually.

If you are using a router such as Linksys, make sure the firmware is the latest revision.

Go to Tools\Internet Options\ and click on the security tab at the top.

Now click on the big green circle with a check in it.

The icon just below the box will now have the green circle.

Click on the Sites button on the right.

Now enter the sites basic url in the add this website to the zone block.

Click on add and it should appear in the window below.

Add any site you are having problems with.

This should help

Good Luck Lee

This also sounds like a known problem with IE and windows xp sp2 installs. Here are some fixes:

I sometimes just have to reload the browser and service pack over but the above steps normally work.
