I know this is going to sound like an odd question, but do these reports have really long names?

I ask this because, since I am at a loss as to what to do next, I Googled your error message, and I found this page on MSDN Support what states this error can occur if you are attempting to programmatically reach a web site with a really long name.

I know this is Crystal related, but it did state that the problem occurs with XP so I thought I would grasp at the straw.
