I have 2 separate users (one a home office the other a user inside a SBS site) who report that they get the error "Internet Explorer cannot open the internet site http://www.aircanada.com/en/home.html
" "Operation aborted"
There was a previous posting similar to this but no evidence that the solution proposed actually fixes the problem for these users.
Problem occurs, as well , when the site is in the trusted sites list and when all air canada cookies are removed.
Microsoft has a knowledge base article 927917 that could explain the problem if everyone got it, but it works for some users!
I called Air Canada and they recommended Firefox, and in a test this works soemwhat better, (at the SBS site) but he was still unable to search for flights, although this error message was not displayed.
I tried running IE with no addons and got the same error.
