Losing .net security trust -- dotnet security

I have a VB.net app running on the 1.0 framework. The exe resides on a
network share and all of the client computers have a full trust configured to
the shared folder from which the exe runs. The app was deployed one year ago
and the clients had no trouble using it. This is a seasonal app and it's
time to use it again. Some clients have reported not being able to access
the app. Investigation found that the security trust had disappeared. Once
it is re-established the app works as expected. My question: what could
possibly be deleting the trust? When asked what has changed on the computer
all of those affected had the same answer "Nothing." (...that they are aware
of when the question is asked.)

Any of the following could have done this:

1. An administrative policy deployment.
2. Installation or patching of any application.
3. "Manual" policy change or reversion to defaults by a sufficiently
privileged user.
4. Alteration of policy by any application run under the identity of a
sufficiently privileged user.

One possibility under #2 is installation of a .NET Framework service pack.
See http://support.microsoft.com/default.aspx?scid=kb;en-us;Q317399 for
details.
