Connection failed for web but only on one account

I have Leopard with the 10.5.1 patch. On one account (of 4), I am unable to browse the web. I can ping web sites and get a response, but if I do something like curl http://www.bbc.co.uk/index.html I get couldn't connect to host.

If I su to from this account to another account and launch the browser, I can browse.

I did have parental control set on this account, but only the filter adult content setting plus time limits. Turning this off seemed to make no difference until I logoff - then I can browse. As soon as I turn on parental control again it fails (even if I have it set to the default, which allows access to all sites). So, there's obviously some garbage causing problems.

Does anyone have any ideas of what I try next?

Many thanks
Paul.

 

Found the answer. The detail I missed out was that I'd had to do a full restore from Time Machine - but it didn't restore one particular directory (which makes me wonder what else may have been missed).

Anyway, details of what to do are here: http://discussions.apple.com/message.jspa?messageID=5945498#5945498
