Clicking on thread titles doesn't work

[SaSi]

In the past couple of weeks I am having a problem with when clicking on message titles in the "View Your Posts" and "View unanswered posts" views of the forum. Internet Explorer shows the message "Cannot find Server"

If I click on a message title, the link generated is like:
http://www.videohelp.com/forum/viewt...167&highlight=

If, on the other hand I click on the "View latest post" link, the link generated is :
http://www.videohelp.com/forum/viewt...234334#1234334
This link works and takes me to the latest posting of the relevant thread.

I tried to manually copy the first link to explorer and tried it with and without the "&highlight=" part. Without the highlight clause it shows Server not found and removing it gives me a message that "only users granted special access can view messages in this forum"

Can it be something wrong with my explorer configuration or is it the forum views doing this?

TIA

does it work if you try reload?

No, reload doesn't work.

I also tried this on two different machines, first on at home (direct dial-up connection) and the second one at work (permanent cable connection via gateway and firewall).
