*We* can't duplicate the error *anywhere*. The two executives won't say if it's happened before. They were using different versions of Windows, different versions of IE and different ISPs. I think one of them was in a different country. AFIAK, they weren't using the coporate VPN. One of them was probably using our own firewall product, but the other probably was not. There was no IE alert, and that is the full extent of the information we have. It's looking like we can't troubleshoot any further without a repeatable error.
