*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.

He's the more helpful one and is certainly capable of understanding that a one-off error like this is actually impossible to find. Trouble is, he is likely to equate his and the other's error as 'repeatable'. The other CEO is not so technically minded. He will see a failure and be almost literally awake at night wondering how many other people are getting it and how much this will affect sales. The fact that no-one else is reporting it and we cannot find anything to even look for is hard for him to understand.
