Padding is invalid and cannot be removed

We're getting a bunch of errors in our web application now that state the following:

An error occurred at 8/21/2006 2:59:33 PM on: /WebResource.axd?d=MwosQXNAI7L8kBKDzT5LZsvGAWnsnq6C3NiO275SEoM1&t=632888115724576432

Padding is invalid and cannot be removed.

Source:mscorlib

I've done some searching and have seen that some problems have been due to web farms with .net 2.0 and a solution was to generate a unique machine key that all servers use.  We aren't using a web farm, though I did try this solution to no avail.

Does anyone out there have any experience with this issue?

Thanks!
