HOW TO: Change the Maximum Size of Attachments in RMTrack


On installation RMTrack sets the maximum available upload and download size for attachments to 10MB.

You may want to consider whether or not it is a good idea to allow uploads larger than 10MB.


A network administrator needs to use IIS's adsutil command.

From a command prompt on your server:

To check the Download size:

  1. Change directory to: c:\inetpub\adminscripts (The ADSUTIL.VBS script is typically located in "c:\inetpub\adminscripts" directory... but this can change depending on your server's configuration)
  2. Run the command: ADSUTIL GET W3SVC/1/Root/RMT/AspBufferingLimit (please see note 1 and 2 below) you should see the response 10485760.
    • Note 1: The '/1' in the command refers to the website that hosts RMT (there may be more than one website on your server - let me know if you need to figure out what number RMTrack uses). The '/RMT' is the virtual directory for RMTrack. The buffer limit can be set for the entire website, but we recommend that you only change RMT.
    • Note 2: When you first execute the adsutil program, you may see the message "This script does not work with WScript". If so, click "OK", then click "Yes" to the prompt "Would you like to register Cscript as your default host for VBScript" and then click "OK" to "Successfully registered Cscript".

To check the Upload size:

  1. ADSUTIL GET W3SVC/1/Root/RMT/AspMaxRequestEntityAllowed

To change the maximum size of attachment upload/download:

  1. Both the above adsutil commands can be used to set the size by changing the GET to SET:

    ADSUTIL SET W3SVC/1/Root/RMT/AspBufferingLimit 10485760
    ADSUTIL SET W3SVC/1/Root/RMT/AspMaxRequestEntityAllowed 10485760

    The recommended limits are 10485760 (10MB) for upload and download.
