I have seen this issue in the past where Norton was the culprit. Disable the program to see if it has any effect. In some situations removing Norton completely was the only solution. Below is a list of other things you may want to try.
Check Firewall/Network Configuration. Make sure that the SSL port (port 443) is open on your network/firewall. This includes software firewalls as well as any hardware firewalls such as a router.
Check your System Cryptogrophy settings:
Control Pannel > Administrative tools > Local Security Settings. Open up Local Policies > Security Options > Verify that "System Cryptogrophy: Use FIPS compliant algorythms for encryption" is set to disabled.
Even though XP should come standard with the correct encryption pack, verify that Internet Explorer Is Using 128-Bit Encryption:
In Internet Explorer, on the Help menu, click About Internet Explorer. The level of encryption on your computer appears next to the words Cipher Strength. Verify that the Cipher Strength value appears as 128-bit. If the Cipher Strength is anything less then 128-bit, download the "Explorer Internet High Encryption Pack" from Microsoft
Delete Temporary Internet Files
There's also a possibility of some corrupted files in your Temporary Internet Files (TIF) storage. You should clear these. In Internet Explorer, on the Tools menu, click Internet Options, and select the General tab. Under Temporary Internet files, click Delete Files, and click OK when you are prompted to confirm the deletion
Configure Security settings for the Trusted sites zone in Internet Explorer:
In Internet Explorer, on the Tools menu, click Internet Options, and select the Security tab. Select Trusted sites, and then click Default Level. Add the secure Web site you are trying to access to the Trusted sites zone. To do so, click Sites, type the address (URL) of the site in the Add this Web site to the zone box. Click Add, click OK, and then click Apply
Clear the Secure Sockets Layer (SSL) slate and AutoComplete history:
In Internet Explorer, on the Tools menu, click Internet Options, and select the Content tab. Under Certificates, click Clear SSL State. Click OK when you receive the message that the SSL cache was successfully cleared. Under Personal information, click AutoComplete. Under Clear AutoComplete history, click Clear Forms. Click OK when you are prompted to confirm the operation.
Verify that Internet Explorer is configured to use SSL 2.0 and SSL 3.0
In Internet Explorer, click on the Tools menu, click Internet Options, and select the Advanced tab. In the Settings box, under the Security header, click to select the Use SSL 2.0 and Use SSL 3.0 check boxes (if they are not already selected), and then click OK
Verify that the Date and Time Settings on Your Computer Are Correct:
If the date on your computer isn't correct, it may prevent you from connecting to secure sites since SSL certificates have an expiration date. To verify that your computer is configured with the correct date and time settings Click Start > click Control Panel > Click Date, Time, Language, and Regional Options, and then click Date and Time, Select the Date & Time tab. Check to make sure that the date and time settings are configured to use the current date and time, and then click OK
