This issue is caused by environment compatibility. WRS protocol will send the URL request longer than 4096, but when asp.net 4.0 is installed onto IIS, it may create another default constraint of default virtual website.

This is a configuration size limit for the requesting URL on ASP.NET, .NET Framework 4 and its supported OS platform running IIS 7.

This can also occur on an environment without OSCE installed.

Refer to this Microsoft article for more information.

Do the following:

  1. Back up the old web.config file.
  2. Download the new web.config file.
  3. Depending on your version, put the new web.config file on the following location:

    C:\Windows\Microsoft.NET\Framework\v2.0.50727\CONFIG(web)
    C:\Windows\Microsoft.NET\Framework64\v2.0.50727\CONFIG(web64)
    C:\Windows\Microsoft.NET\Framework\v4.0.30319\CONFIG(web)
    C:\Windows\Microsoft.NET\Framework64\v4.0.30319\CONFIG(web64)

  4. Restart the IIS service.
  5. Restart the Trend Micro Local Web Classification Server service.
