Re: ASP.NET web app works on some, not all, workstations

Tech Tip: Click here to run a free scan for Windows Errors and optimize PC performance

I have a scanning application that used to give me odd errors on posting
scanned images. The culprit was the browser who would take a cached version
of one of the pages instead of going for it to the server.

Start from finding out what server error causes the 'Internal Server Error'.
For that, you may need to ask the developers to provide better error
reporting or at least put the exception messages into the http response.
With that, you can use an http analyzer tool to see the errors. You can also
look in the server's http logs but they are not always helpful.

I have a client that has contracted with a bank to process checks over the
Internet. The solution includes a check scanner and APS.NET web
application.

The application does not work for all workstations at the client site.
There are two laptop computers than can run the web application and all
it's
functions w/o failure. They have been able to do this from day one w/o
modification.

No other PC workstations can run all of the web application functions.
Some
page return an 'Internal Server Error' message. The page displayed is a
custom error page with no other details.

For some reason the owners of the web application have no clue why their
application will work for some, but not others.

Some facts:
All workstations are XP SP2
There is a mix of IE6 and 7 but this does not seem to be an issue because
each laptop has a different version (1 has IE7, the other has IE6).
Application will not allow browsers other than IE5.5 or higher (Firefox is
out)
The application requires an ActiveX control to interface with the scanner.
Check scanning is not an issue.

I have tried the following:
Disabling local Windows Firewall, Defender, AV
Running as local administrator

Has anyone seen something like this before?
