Failed Trace.Assert statement popuping up message on web server.

[Guest]

We've started testing an ASP.NET 2.0 project on one of our web servers with
the client. Within the various assemblies the web project uses are Trace and
Debug assertions to assist with our diagnostics.

Now according to the .NET framework documentation, failed assertions from a
web project should not be popping up a message box containing the assertion
message. However, one the test server we are getting popup messages when the
assertion fails. This is only occuring on the one web server.

Does anybody know if some 3rd party tool could be responsible for this or
some IIS setting?

Many thanks
