Windows XP is unable to access dropbox.com

I have a client running WindowsXP.  When they try to access www.dropbox.com, IE fails to load the page with the error message "IE cannot load the webpage".  However, the website can be successfully loaded from Google Chrome.

The Dropbox installer is also unable to download any of the installer files from the dropbox server during the installation.  This causes the installation to fail.

nslookup correctly resolves dropbox.com.  I am also able to ping dropbox.com

The problem occurs on both the administrator account as well as a user account with administrative privileges.

I ran malwarebytes, combofix, adwcleaner, and cleaned up any issues that they found.

Does anyone know what could be causing this block, and yet Google Chrome is not affected?

what version of IE do you have?
do you have set some proxy or restricted sites for IE?

I can access https://www.dropbox.com/ with both IE8 and Firefox on this XP machine so I don't believe it is an XP problem.  Do you have any add-ons in IE8?  What anti-virus are you using?

Try resetting IE to factory defaults, this includes ensuring the advanced settings are reset.

What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

Are the TLS 1.x boxes ticked in Tools > Internet optionsAdvanced tab > scroll to the bottom in the Settings box, underneath Security?

If not, try ticking the boxes and then access the Dropbox site again.

EDIT: I would also disable SSL 3.0 while you are in the above section as there has been a vulnerability that has been recently discovered which, when exploited, allows an attacker to steal confidential information such as cookies and passwords.

Because of this vulnerability, companies are disabling https access over SSL 3.0 which can be the cause of your issue here. The recommended action is to enable TLS 1.0, 1.1, and 1.2 in IE.

@helpfinder:  The client is using IE version 8.0, with no proxy configured

@roshan: I reset IE to the default settings, but it had no effect

@vbits: I checked the settings and SSL3, and TLS 1.0 were enabled.  I disabled SSLv3, but that had no effect.

I was wondering why there was no option for TLSv1.1, or TLSv1.2, and discovered that the system only had Service Pack 2 installed.  Upgrading to Service Pack 3 resolved the connectivity problem with dropbox.com.  However, the "internet options -> Advanced -> Security" only shows TLSv1.0.  I guess IE v8.0 does not support TLSv1.1 or TLSv1.2.

Windows required service pack 3 to be installed in order to resolve the issue.
