Description:

In some circumstances, when an Analyst copies a Change Order, the following error appears:

HTTP Error 404.15 - Not Found

The request filtering module is configured to deny a request where the query string is too long.
Please see the new attachment.

This problem has been reported with users running Fire Fox 26 so far.

Solution:

Refer to the following Microsoft documentation:

http://www.iis.net/configreference/system.webserver/security/requestfiltering/requestlimits

Request Limits <requestLimits>

"Overview:

The <requestLimits> element specifies limits on HTTP requests that are processed by the Web server. These limits include the maximum size of a request, the maximum URL length, and the maximum length for a query string. In addition, the<requestLimits> element can contain a collection of user-defined HTTP header limits in the <headerLimits> element, which allows you to define custom settings on HTTP headers."

The document mentioned provides explanations on what to change in IIS to accommodate the string and resolve the problem.
