Vista Parental Controls Issue

[AnonymouseUser]

I've been scratching my head over this issue for a couple of hours, and finally zeroed in on the issue. It just doesn't make sense and I can't find a way to fix it, so I am turning to the collective knowledge of AT for assistance.

It all started with a simple request: SO attempted to join the Viadeo network. The website initially loads just fine, but clicking the "Register" button does nothing but hang indefinitely. It doesn't matter which browser is used, none of them will work (Opera, IE, Chrome, and Firefox all failed).

We have added Parental Controls to the SO's account to prevent SO's daughter from accessing certain sites, but aside from those few websites and a time restriction there are no other restrictions enabled. If we log in to the Administrator account there are no problems accessing the website. I've verified this identical behavior on the daughter's computer (also Vista) and in a Vista VM.

I have no issues connecting from my Linux computer or by using an anonymous web proxy on Vista when using the Standard User with Parental Controls enabled.

To duplicate:
Using a Standard User account, enable Parental Controls, but disable everything. You will no longer be able to access the registration page on Viadeo. You can bypass the link and go directly to the registration page @ join.viadeo.com, but you still won't be able to register.

Does anyone have any idea why this is happening and how to fix it?

EDIT >> I even tried running Firefox as an Administrator from the Standard User account, but it also hangs.

I don't have net on my Vista box, so I can't check myself, but perhaps the desired site is accessing a verboten site through the register button? Maybe a 3rd party cookie, or something like that?

Even when there are no filters it still blocks the site? It shouldn't be blocking anything.

Can anyone check to see if the behavior is the same on Win 7?

Does this look relevant? My networking is very weak, but perhaps it's some kind of block that doesn't pertain specifically to parental controls. Maybe it's some kind of UAC type issue.

IPv6 connection filtering
The IPv6 connection filtering system is one of several ways in which Windows Vista
looks to protect user data as it is transmitted across networks. The security of outbound
packets is enhanced by the flittering, which allows the user to specific both source and
destination IP addresses and apply rules about port ranges through which the data is to
be transmitted. By controlling this information – at the risk of becoming too technical –
the user is able to enhance the effectiveness of their overall security by encrypting data
and applying stringent limits to the methods used to send the data, reducing the risk of
interception by third-parties.
The IPv6 offers IPsec as a fully integrated feature. It allows the acceptance or denial of
connections based on security certificates and other elements such as Kerberos
authentication protocol.
The system also establishes that various types of encryption may be required for
different connections and establishes the basis for providing system users with an
effective means of securing the necessary information using a wizard to handle complex
configuration. Windows Firewall, for example, can be configured to allow traffic based
on whether it is secured by IPsec.

Not very thorough. Maybe a white paper on parental controls, or Vista's network security would be helpful. I'm not finding much.

That sounds like it could be a possible culprit, but I did disable IPv6** on one machine for testing purposes and nothing changed. FWIW, I also disabled TCP/IP auto tuning, Windows Firewall, Defender, and Avira anti-virus. I neglected to mention this since I had proven that Parental Controls that was at the root of the issue and didn't think IPv6 filtering could have been a part of the issue.

** While I did disable IPv6, I only disabled one aspect of it. From this page, I used the second of the "Fix it for me" solutions (Use IPv4 instead of IPv6 in prefix policies). Still, it sounds like I would need to manually create a policy for the IPv6 filtering to work.
