Security alert box - cetificates

[Guest]

I just began having a problem with secure (https) sites. Whenever I go to a
secure page I get a "Security Alert" message box which has the statement
"Security certificate has expired or is not valid" and asking if I want to
proceed. There are 3 buttons - "yes", "no" and "view certificate". This just
started after someone was troubleshooting my system and playing with some
configuration things to find a problem I was having with my dial-up modem.
Note: I usually use an ethernet connection. It has otherwise been working
fine before. Running XP Pro. Do not have the problem on a 2nd machine.

I connect through a router and am not running any firewall software.

Difficulty accessing secure sites is not only thru the browser. I run a
program which handles it's own connection to it's companies server and it
cannot access the web either.

Can anyone tell me what the problem might be?

Check the time on your computer to make sure it is correct and be sure to
check it all - month, year, time zone, etc. --- Steve
