Only a small number of users were able to access our ASP.NET application during a demonstration - why?

P: n/a

Today and tomorrow we're demonstrating our ASP.NET application to the
external business customers who will be using it (this is what would best be
called a B2B application). I've set things up so that the users
automatically go against our test server for the database. We'll "go live"
next week Monday.

For some reason, while demonstrating the app, it was causing lots of errors
for users. It became apparent that the issue was one of the number of users
connecting. We did not have a lot of users - at the time there were
probably all of 25 users hitting against the website and database. That's
not what I would call overwhelming, so why did it fail? Is there some sort
of limit to the number of concurrent users that IIS will accommodate? We've
using Crystal Reports for .NET, could that be a problem? (No one was
actually running a report at the time, so I don't know why that could cause
a problem, but could it?) We have ISA on a server which redirects a server
with IIS on it and then the database is on a test server (a single processor
machine with SQL Server on it. This test server is an old desktop system
that was converted to a server). Could that be the problem?

The error message was not very helpful. It said something like, "If you put
this setting into your Web.Config file, you will get a better error
message". Since we were doing this during a demonstration with a room full
of people, the guy who was running the demo didn't stop to print out the
error message.

the OS is Windows 2000 Server running on an old Gateway E-4200. (i.e.:
hardware wise, this is NOT a real server, it is an old Windows 98 machine
that we wiped the OS from and then installed Windows 2000 Server onto, so
that we could have a test machine as a server.)

Maybe get Application Center Test, record a couple test scripts, and try to
reproduce the error in a controlled environment....also, your application
should have error logging facilities (for this kind of situation).

Other than that, you've provided nothing to go on :( sorry.
