Work, then I'd have to assume it be part of the akamai redirection stuff, plus considering you probably use *SOME* kind of caching proxy.

Given all that, it would be rather easy to cut out the proxy for a bit and try again for them.

Now, if this happened at HOME, was it when connected to the VPN or just straight internet?

If just straight internet, then you've got a real problem to track down. It could be settings left over from connecting to the VPN, along with the proxy and akamai redirection.

If it happened while connected to the corporate network via VPN, well you are back to the same problem as being at work.

There is to many unknowns. Especially if they don't have machines as locked down as the rest of the corporate machines. Vista, perhaps?

Cheers.
