I was trying to set up an e-mail template today with an attachment that was nearly 8MB in size. Upon trying to attach the file, I got an error message: "Maximum request length exceeded."

Details: 
Application_OnError - Unhandled Exception: 
System.Web.HttpException: Maximum request length exceeded. 
at System.Web.HttpRequest.GetEntireRawContent() 
at System.Web.HttpRequest.GetMultipartContent() 
at System.Web.HttpRequest.FillInFormCollection() 
at System.Web.HttpRequest.get_Form() 
at System.Web.UI.Page.GetCollectionBasedOnMethod() 
at System.Web.UI.Page.DeterminePostBackMode() 
at System.Web.UI.Page.ProcessRequestMain()

Upon doing some research, I discovered that the default setting for file attachments in the Helpdesk solution is 4MB.

I also found that you can increase this to meet your needs. Here is what you need to do:

1. On your Notification Server, open the web.config file with your favorite text editor.

   It is located in \Program Files\Altiris\Helpdesk\AeXHD

2. Locate the following line in this file:
   

   </system.web>
   
   

3. Right above this line, add the following line:
   

   <httpRuntime maxRequestLength="8192"/>
   
   

   NOTE: the example above would set the file size to 8MB, but you can adjust this number to meet your specific needs.
4. Save the web.config file.
5. Restart IIS.

Now you can add file attachments up to the size you specified.
