When you try to run a large report on SCCM 2007 you might come across this error “HTTP 500 Internal Server Error” and page shows “The website cannot display the page” . This is the default behavior of IIS which has a default buffer size limited 4 MB for ASP response. To resolve the issue we need to increase the size of ASP response to resolve the HTTP 500 Internal Server Error .
-On SCCM server go to Start—>Run—>cmd—>Click Ok—>Type cd /d %systemdrive%\inetpub\adminscripts -–>Enter—> type cscript.exe adsutil.vbs SET w3svc/aspbufferinglimit 67108864
( buffer size increased to 64MB)
