Can’t Access HTTPS Sites

[DonSchmidt]

About 2 weeks ago, I started to have problems accessing https sites. Not all, but most. In diagnosing the problem, I connected another computer to the router/modem and have the same problem. Both computers worked before. Tech support at my ISP had me try some of the same things that I read in the discussion threads, but the solution would work for 1 time after I re-booted. I was pretty much convinced that the problem was with the router/modem or the ISP server until I connected a new laptop to the network. The laptop works flawlessly. I am baffled. I have run the Windows repair function, registered the dll files that were suggested in the forum, cleared the DNS cache, reset the router and still have the problem. I have the problem with IE6, IE7, Firefox and Opera.

The problem occurred shortly after I de-installed leftover files from my former ISP, Earthlink. No changes were made to the second computer, which worked before.

My main computer is running Windows XP Pro SP3, the second Computer runs Windows XP Home Edition, and the laptop is running Windows Vista Home Premium.

This appears to be a problem shared by many people. Does anyone have a solution to share?

Hi and welcome to the Daniweb forums :).

Download Dial-a-Fix and run it. Select the 'Check all' (green arrow) and then hit 'GO.'
Reboot when done and see how things are now.

Thanks for your assistance. I tried it on both computers, but am still having the same problem. Any other ideas?

Download and run Winsockfix from here http://www.softpedia.com/get/Tweak/Network-Tweak/WinSockFix.shtml

If no luck, try this;

Download LSPfix from here
On the opening screen, click the "I know what I'm doing" checkboxand then click Finish.

I tried them both, but still no luck. Could it be a Home Network setting that is no longer working?

[crunchie]

Not sure. Have you tried doing a system restore to before the problem started?

[DonSchmidt]

I haven't because of installing other updates and SP3 since then.
