Our client was receiving this error each time they visited their ISP’s webmail logon page.

The problem was due to a corrupt cookie previously generated by the website.   The easy solution is to delete all your cookies

To do this in IE go into Tools, Internet Options, then look for Browsing history




Press delete, then just select cookies




However, you may not want to delete all of your cookies as, after all, only one of them is corrupt.

In this case (IE and XP) – the cookies were stored under:

c:\documents and settings\<username>\Cookies

Find the cookie relating to the website you’re having trouble with, delete it and you should be able to access the site again.
