Increasing the maximum query string on the NDES server

Increase the size of the query strings that the Cloud Extender® uses to request certificates from NDES for mobile devices.

About this task

By default, IIS is installed with the Request Filtering feature enabled and the default Maximum Query String Size set to 2048 bytes. Any certificate request that requires a longer query string size is filtered out. The Cloud Extender uses query strings during certificate requests that are greater than 2048 bytes. Increase the size of the query string value to enable Cloud Extender to request certificates against NDES.

Procedure

  1. Log on to the NDES server with administrative credentials.
  2. Select Start > Cmd, and then right-click Run As Admin.
  3. From the command prompt, copy the following command and press Enter. windir%\system32\inetsrv\appcmd set config /section:requestFiltering /requestLimits.maxQueryString:8192
    The maximum query limit is set to 8192 bytes.
  4. Restart IIS.
