Configure IIS Response Buffering Limit on ConfigMgr reporting points

 If you get a HTTP 500 error when trying to watch a report e.g "History - Specific task sequence advertisements run on a specific computer"

With show friendly HTTP error messages enabled in IE:
The website cannot display the page
 HTTP 500 

This error (HTTP 500 Internal Server Error) means that the website you are visiting had a server problem which prevented the webpage from displaying.

Show friendly HTTP error messages disabled in IE:
An error occurred on the server when processing the URL. Please contact the system administrator.

You can try to solve this by increasing the ASP "Response Buffering Limit" for the site hosting the reporting point.

The following command sets the limit to 8 MB (8388608) , The default value is 4 MB (4194304)

C:\Windows\System32\inetsrv>appcmd.exe set config "Default Web Site" -section:system.webServer/asp /limits.bufferingLimit:"8388608" /commit:apphost
