To get a more detailed error message for diagnostic, you will need to comment out two sections of the web.config file for the METTEAM website which is typically located in the root of the METTEAM website files on the server hosting MET/TEAM in this location:
C:\inetpub\wwwroot\METTEAM\
NOTE: Before editing your Web.config file, be sure to have a copy of the file in a safe place!
To comment out a section, place "<!--" before the section you are commenting out and then "-->" after the section.
Comment out the following section of your web.config file (in the <system.Web> section):
<!-- Redirect to the error page if there is a critical bug. -->
<customErrors mode="RemoteOnly" redirectMode="ResponseRewrite" defaultRedirect="~/500.aspx">
<error statusCode="404" redirect="~/404.aspx"/>
<error statusCode="500" redirect="~/500.aspx"/>
</customErrors>
And then also comment out the following section from the <system.webServer> section:
<httpErrors errorMode="Custom">
<remove statusCode="404"/>
<error statusCode="404" path="404.html" responseMode="File"/>
<remove statusCode="500"/>
<error statusCode="500" path="500.html" responseMode="File"/>
</httpErrors>
Then, on a browser running directly on the computer hosting the MET/TEAM website, typically as server, attempt the action again. This will result in a more detailed error message. If necessary, capture the message so you can share it with softwaresupport@flukecal.com .
