Very little info provided about your Operating system Version/SP or IE
version and does it happen with all sites or some!

Did you scan the machine for amlware and viruses lately?
Check that the local computer clock is accurate.
Reset IE7 Settings (RIES)
http://support.microsoft.com/kb/923737

Reboot and try the sites, does it help?

# Click start >> Control Panel >> Double Click Network and Internet
Connections >> Double click Internet Options, on the IE Properties window
you will see these Options:
General | Security | Privacy | Content | Connections | Programs
| Advanced .
Click Content Tab then click Certificate Button. On the Certificates scrol <
> to get the Untrusted Publisher and there remove the Certificate for the
sites you have problem with!

Click On Adavanced tan and scroll down to this options under Security and
Uncheck the check boxes:
[ ] Check for server certificate revocation*
[ ] Check for Publisher's certificate revocation

Click [Apply] then [OK]
Are you able to access the sites without any error, if you do then please
recheck these two check boxes back:
[ ] Check for server certificate revocation*
[ ] Check for Publisher's certificate revocation
